Enterprises are using Hadoop for interactive real-time data processing via projects such as the Stinger Initiative. We describe two new HDFS features – Centralized Cache Management and Heterogeneous Storage – that allow applications to effectively use low latency storage media such as Solid State Disks and RAM. In the first part of this talk, we discuss Centralized Cache Management to coordinate caching important datasets and place tasks for memory locality. HDFS deployments today rely on the OS buffer cache to keep data in RAM for faster access. However, the user has no direct control over what data is held in RAM or how long it?s going to stay there. Centralized Cache Management allows users to specify which data to lock into RAM. Next, we describe Heterogeneous Storage support for applications to choose storage media based on their performance and durability requirements. Perhaps the most interesting of the newer storage media are Solid State Drives which provide improved random IO performance over spinning disks. We also discuss memory as a storage tier which can be useful for temporary files and intermediate data for latency sensitive real-time applications. In the last part of the talk we describe how administrators can use quota mechanism extensions to manage fair distribution of scarce storage resources across users and applications.

HBase provides an LRU based on heap cache but its size (and so the total data size that can be cached) is limited by Java’s max heap space. This talk highlights our work under HBASE-11425 to allow the HBase read path to work directly from the off-heap area.
The document evaluates the performance of HBase version 0.20.0 on a small cluster. It describes the testbed setup including hardware specifications and Hadoop/HBase configuration parameters. A series of experiments are run to test random reads, random writes, sequential reads, sequential writes, and scans. The results show significant performance improvements over previous versions, getting closer to the performance levels of Google BigTable as reported in their paper.
HBase and HDFS: Understanding FileSystem Usage in HBaseenissoz
This document discusses file system usage in HBase. It provides an overview of the three main file types in HBase: write-ahead logs (WALs), data files, and reference files. It describes durability semantics, IO fencing techniques for region server recovery, and how HBase leverages data locality through short circuit reads, checksums, and block placement hints. The document is intended help understand HBase's interactions with HDFS for tuning IO performance.
Journey to Stability: Petabyte Ceph Cluster in OpenStack CloudPatrick McGarry
Cisco Cloud Services provides an OpenStack platform to Cisco SaaS applications using a worldwide deployment of Ceph clusters storing petabytes of data. The initial Ceph cluster design experienced major stability problems as the cluster grew past 50% capacity. Strategies were implemented to improve stability including client IO throttling, backfill and recovery throttling, upgrading Ceph versions, adding NVMe journals, moving the MON levelDB to SSDs, rebalancing the cluster, and proactively detecting slow disks. Lessons learned included the importance of devops practices, sharing knowledge, rigorous testing, and balancing performance, cost and time.
This document summarizes a presentation about optimizing for low latency in HBase. It discusses how to measure latency, the write and read paths in HBase, sources of latency like garbage collection and compactions, and techniques for reducing latency like streaming puts, block caching, and timeline consistency. The key points are that single puts can achieve millisecond latency while garbage collection and machine failures can cause pauses of 10s of milliseconds to seconds, and optimizing for the "magical 1%" of requests after the 99th percentile is important to improve average latency.
Apache HBase, Accelerated: In-Memory Flush and Compaction HBaseCon
Eshcar Hillel and Anastasia Braginsky (Yahoo!)
Real-time HBase application performance depends critically on the amount of I/O in the datapath. Here we’ll describe an optimization of HBase for high-churn applications that frequently insert/update/delete the same keys, such as for high-speed queuing and e-commerce.
This document summarizes a presentation about optimizing HBase performance through caching. It discusses how baseline tests showed low cache hit rates and CPU/memory utilization. Reducing the table block size improved cache hits but increased overhead. Adding an off-heap bucket cache to store table data minimized JVM garbage collection latency spikes and improved memory utilization by caching frequently accessed data outside the Java heap. Configuration parameters for the bucket cache are also outlined.

HBaseCon 2012 | HBase Coprocessors – Deploy Shared Functionality Directly on ...Cloudera, Inc.
HBase Coprocessors allow user code to be run on region servers within each region of an HBase table. Coprocessors are loaded dynamically and scale automatically as regions are split or merged. They provide hooks into various HBase operations via observer classes and define an interface for custom endpoint calls between clients and servers. Examples of use cases include secondary indexes, filters, and replacing MapReduce jobs with server-side processing.
Optimizing Apache HBase for Cloud Storage in Microsoft Azure HDInsightHBaseCon
Nitin Verma, Pravin Mittal, and Maxim Lukiyanov (Microsoft)
This session presents our success story of enabling a big internal customer on Microsoft Azure’s HBase service along with the methodology and tools used to meet high-throughput goals. We will also present how new features in HBase (like BucketCache and MultiWAL) are helping our customers in the medium-latency/high-bandwidth cloud-storage scenario.
Speaker: Vladimir Rodionov (bigbase.org)
This talks introduces a totally new implementation of a multilayer caching in HBase called BigBase. BigBase has a big advantage over HBase 0.94/0.96 because of an ability to utilize all available server RAM in the most efficient way, and because of a novel implementation of a L3 level cache on fast SSDs. The talk will show that different type of caches in BigBase work best for different type of workloads, and that a combination of these caches (L1/L2/L3) increases the overall performance of HBase by a very wide margin.
The document summarizes the HBase 1.0 release which introduces major new features and interfaces including a new client API, region replicas for high availability, online configuration changes, and semantic versioning. It describes goals of laying a stable foundation, stabilizing clusters and clients, and making versioning explicit. Compatibility with earlier versions is discussed and the new interfaces like ConnectionFactory, Connection, Table and BufferedMutator are introduced along with examples of using them.
Rigorous and Multi-tenant HBase Performance MeasurementDataWorks Summit
The document discusses techniques for rigorously measuring HBase performance in both standalone and multi-tenant environments. It begins with an overview of HBase and the Yahoo! Cloud Serving Benchmark (YCSB) for evaluating databases. It then discusses best practices for cluster setup, data loading, and benchmarking techniques like warming the cache, setting target throughput, and using appropriate workloads. Finally, it covers challenges in measuring HBase performance when used alongside other frameworks like MapReduce and Solr in a multi-tenant setting.
HBase 2.0 is the next stable major release for Apache HBase scheduled for early 2017. It is the biggest and most exciting milestone release from the Apache community after 1.0. HBase-2.0 contains a large number of features that is long time in the development, some of which include rewritten region assignment, perf improvements (RPC, rewritten write pipeline, etc), async clients, C++ client, offheaping memstore and other buffers, Spark integration, shading of dependencies as well as a lot of other fixes and stability improvements. We will go into technical details on some of the most important improvements in the release, as well as what are the implications for the users in terms of API and upgrade paths. Existing users of HBase/Phoenix as well as operators managing HBase clusters will benefit the most where they can learn about the new release and the long list of features. We will also briefly cover earlier 1.x release lines and compatibility and upgrade paths for existing users and conclude by giving an outlook on the next level of initiatives for the project.

The document also covers challenges in achieving good multi-tenant performance across HBase, MapReduce and Apache Solr.
HBaseCon 2012 | HBase and HDFS: Past, Present, Future - Todd Lipcon, ClouderaCloudera, Inc.
Apache HDFS, the file system on which HBase is most commonly deployed, was originally designed for high-latency high-throughput batch analytic systems like MapReduce. Over the past two to three years, the rising popularity of HBase has driven many enhancements in HDFS to improve its suitability for real-time systems, including durability support for write-ahead logs, high availability, and improved low-latency performance. This talk will give a brief history of some of the enhancements from Hadoop 0.20.2 through 0.23.0, discuss some of the most exciting work currently under way, and explore some of the future enhancements we expect to develop in the coming years. We will include both high-level overviews of the new features as well as practical tips and benchmark results from real deployments.
This talk delves into the many ways that a user has to use HBase in a project. Lars will look at many practical examples based on real applications in production, for example, on Facebook and eBay and the right approach for those wanting to find their own implementation. He will also discuss advanced concepts, such as counters, coprocessors and schema design.
The document discusses several key topics in Apache HBase:
1. Procedure version 2 introduces a new framework for running operations like create/drop table and region assignment as procedures with distinct phases.
2. Assignment Manager version 2 uses procedures and improves region assignment and load balancing.
3. Backup/restore now supports HDFS, S3, ADLS and WASB. Snapshots can also be used for backup.
4. Compacting memstore allows in-memory flushing and compaction to improve performance through pipelining.
HBaseCon 2012 | Base Metrics: What They Mean to You - ClouderaCloudera, Inc.
If you’re running an HBase cluster in production, you’ve probably noticed that HBase shares a number of useful metrics about everything from your block cache performance to your HDFS latencies over JMX (or Ganglia, or just a file). The problem is that it’s sometimes hard to know what these metrics mean to you and your users. Should you be worried if your memstore SizeMB is 1.5GB? What if your regionservers have a hundred stores each? This talk will explain how to understand and interpret the metrics HBase exports. Along the way we’ll cover some high-level background on HBase’s internals, and share some battle tested rules-of-thumb about how to interpret and react to metrics you might see.
The document provides an overview of new features in HDFS in Hadoop 2, including:
- A new appendable write pipeline that allows files to be reopened for append and provides primitives like hflush and hsync.
- Support for multiple namenode federation to improve scalability and isolate namespaces.
- Namenode high availability using techniques like ZooKeeper and a quorum journal manager to avoid single points of failure.
- A new file system snapshots feature that allows point-in-time recovery through copy-on-write snapshots without data copying.
You’ve successfully deployed Hadoop, but are you taking advantage of all of Hadoop’s features to operate a stable and effective cluster? In the first part of the talk, we will cover issues that have been seen over the last two years on hundreds of production clusters with detailed breakdown covering the number of occurrences, severity, and root cause. We will cover best practices and many new tools and features in Hadoop added over the last year to help system administrators monitor, diagnose and address such incidents.
The second part of our talk discusses new features for making daily operations easier. This includes features such as ACLs for simplified permission control, snapshots for data protection and more. We will also cover tuning configuration and features that improve cluster utilization, such as short-circuit reads and datanode caching.
The document discusses improvements to HDFS that allow it to leverage memory as a storage medium. Key points include:
- HDFS 2.3 introduced memory as a storage medium, with RAM disks providing persistence across restarts.
- HDFS 2.6 introduced storage policies that allow applications to target different storage media like SSD or memory.
- The Centralized Cache Management feature loads hot data into memory pools to enable zero-copy reads.
- The Lazy Persist Writes feature allows applications to write to memory and have HDFS asynchronously write to persistent storage, reducing latency.
- Future work includes improving caching, short-circuit writes, and the Memfs layered file system to provide more flexible
Are you taking advantage of all of Hadoop’s features to operate a stable and effective cluster? Inspired by real-world support cases, this talk discusses best practices and new features to help improve incident response and daily operations. Chances are that you’ll walk away from this talk with some new ideas to implement in your own clusters.
Hadoop Operations - Best Practices from the FieldDataWorks Summit
This document discusses best practices for Hadoop operations based on analysis of support cases. Key learnings include using HDFS ACLs and snapshots to prevent accidental data deletion and improve recoverability. HDFS improvements like pausing block deletion and adding diagnostics help address incidents around namespace mismatches and upgrade failures. Proper configuration of hardware, JVM settings, and monitoring is also emphasized.
The current major release, Hadoop 2.0 offers several significant HDFS improvements including new append-pipeline, federation, wire compatibility, NameNode HA, Snapshots, and performance improvements. We describe how to take advantages of these new features and their benefits. We cover some architectural improvements in detail such as HA, Federation and Snapshots. The second half of the talk describes the current features that are under development for the next HDFS release. This includes much needed data management features such as backup and Disaster Recovery. We add support for different classes of storage devices such as SSDs and open interfaces such as NFS; together these extend HDFS as a more general storage system. Hadoop has recently been extended to run first-class on Windows which expands its enterprise reach and allows integration with the rich tool-set available on Windows. As with every release we will continue improvements to performance, diagnosability and manageability of HDFS. To conclude, we discuss the reliability, the state of HDFS adoption, and some of the misconceptions and myths about HDFS.
Building a Distributed File System for the Cloud-Native EraAlluxio, Inc.
Big Data Bellevue Meetup
May 19, 2022
For more Alluxio events: https://alluxio.io/events/
Speaker: Bin Fan (Founding Engineer & VP of Open Source, Alluxio)
Today, data engineering in modern enterprises has become increasingly more complex and resource-consuming, particularly because (1) the rich amount of organizational data is often distributed across data centers, cloud regions, or even cloud providers, and (2) the complexity of the big data stack has been quickly increasing over the past few years with an explosion in big-data analytics and machine-learning engines (like MapReduce, Hive, Spark, Presto, Tensorflow, PyTorch to name a few).
To address these challenges, it is critical to provide a single and logical namespace to federate different storage services, on-prem or cloud-native, to abstract away the data heterogeneity, while providing data locality to improve the computation performance. [Bin Fan] will share his observation and lessons learned in designing, architecting, and implementing such a system – Alluxio open-source project — since 2015.
Alluxio originated from UC Berkeley AMPLab (used to be called Tachyon) and was initially proposed as a daemon service to enable Spark to share RDDs across jobs for performance and fault tolerance. Today, it has become a general-purpose, high-performance, and highly available distributed file system to provide generic data service to abstract away complexity in data and I/O. Many companies and organizations today like Uber, Meta, Tencent, Tiktok, Shopee are using Alluxio in production, as a building block in their data platform to create a data abstraction and access layer. We will talk about the journey of this open source project, especially in its design challenges in tiered metadata storage (based on RocksDB), embedded state-replicate machine (based on RAFT) for HA, and evolution in RPC framework (based on gRPC) and etc.
WANdisco Non-Stop Hadoop: PHXDataConference Presentation Oct 2014 Chris Almond
Hadoop has quickly evolved into the system of choice for storing and processing Big Data, and is now widely used to support mission-critical applications that operate within a ‘data lake’ style infrastructures. A critical requirement of such applications is the need for continuous operation even in the event of various system failures. This requirement has driven adoption of multi-data center Hadoop architectures, a.k.a geo-distributed or global Hadoop. In this session we will provide a brief introduction to WANdisco, then dig into how our Non-Stop Hadoop solution addresses real world use cases, and also a show live demonstration of Non-Stop namenode operation across two WAN connected hadoop clusters.
The document discusses evolving HDFS to support generalized storage containers in order to better scale the number of files and blocks. It proposes using block containers and a partial namespace approach to initially scale to billions of files and blocks, and eventually much higher numbers. The storage layer is being restructured to support various container types for use cases beyond HDFS like object storage and HBase.
HDFS (Hadoop Distributed File System) is designed to store very large files across commodity hardware in a Hadoop cluster. It partitions files into blocks and replicates blocks across multiple nodes for fault tolerance. The document discusses HDFS design, concepts like data replication, interfaces for interacting with HDFS like command line and Java APIs, and challenges related to small files and arbitrary modifications.
The Hadoop Distributed File System is the foundational storage layer in typical Hadoop deployments. Performance and stability of HDFS are crucial to the correct functioning of applications at higher layers in the Hadoop stack. This session is a technical deep dive into recent enhancements committed to HDFS by the entire Apache contributor community. We describe real-world incidents that motivated these changes and how the enhancements prevent those problems from reoccurring. Attendees will leave this session with a deeper understanding of the implementation challenges in a distributed file system and identify helpful new metrics to monitor in their own clusters.
Best Practices for Virtualizing Apache HadoopHortonworks
Join this webinar to discuss best practices for designing and building a solid, robust and flexible Hadoop platform on an enterprise virtual infrastructure. Attendees will learn the flexibility and operational advantages of Virtual Machines such as fast provisioning, cloning, high levels of standardization, hybrid storage, vMotioning, increased stabilization of the entire software stack, High Availability and Fault Tolerance. This is a can`t miss presentation for anyone wanting to understand design, configuration and deployment of Hadoop in virtual infrastructures.
Big data refers to large and complex datasets that are difficult to process using traditional methods. Key challenges include capturing, storing, searching, sharing, and analyzing large datasets in domains like meteorology, physics simulations, biology, and the internet. Hadoop is an open-source software framework for distributed storage and processing of big data across clusters of computers. It allows for the distributed processing of large data sets in a reliable, fault-tolerant and scalable manner.
- HDFS Federation allows Hadoop to scale beyond the limitations of a single namespace by splitting the namespace across multiple independent namenodes. Each namenode manages its own namespace volume consisting of a namespace and block pool.
- A client-side mount table provides a virtual unified namespace by mapping namespace volumes to namenodes, hiding the federation details from users and applications.
- HDFS Federation provides wire compatibility by requiring clients to use the same version of Hadoop as the servers, and supports existing HDFS functionality like append, sticky bits, and new APIs like FileContext.
1. beyond mission critical virtualizing big data and hadoopChiou-Nan Chen
Virtualizing big data platforms like Hadoop provides organizations with agility, elasticity, and operational simplicity. It allows clusters to be quickly provisioned on demand, workloads to be independently scaled, and mixed workloads to be consolidated on shared infrastructure. This reduces costs while improving resource utilization for emerging big data use cases across many industries.
Presentation on 2013-06-27, Workshop on the future of Big Data management, discussing hadoop for a science audience that are either HPC/grid users or people suddenly discovering that their data is accruing towards PB.
The other talks were on GPFS, LustreFS and Ceph, so rather than just do beauty-contest slides, I decided to raise the question of "what is a filesystem?", whether the constraints imposed by the Unix metaphor and API are becoming limits on scale and parallelism (both technically and, for GPFS and Lustre Enterprise in cost).
Then: HDFS as the foundation for the Hadoop stack.
All the other FS talks did emphasise their Hadoop integration, with the Intel talk doing the most to assert performance improvements of LustreFS over HDFSv1 in dfsIO and Terasort (no gridmix?), which showed something important: Hadoop is the application that add DFS developers have to have a story for
How the Development Bank of Singapore solves on-prem compute capacity challen...Alluxio, Inc.
The Development Bank of Singapore (DBS) has evolved its data platforms over three generations to address big data challenges and the explosion of data. It now uses a hybrid cloud model with Alluxio to provide a unified namespace across on-prem and cloud storage for analytics workloads. Alluxio enables "zero-copy" cloud bursting by caching hot data and orchestrating analytics jobs between on-prem and cloud resources like AWS EMR and Google Dataproc. This provides dynamic scaling of compute capacity while retaining data locality. Alluxio also offers intelligent data tiering and policy-driven data migration to cloud storage over time for cost efficiency and management.
Tachyon is a memory-centric distributed storage system that provides reliable data sharing at memory speed across various cluster computing frameworks. It addresses issues with current storage systems like slow data sharing due to disk writes, cache loss when processes crash, and in-memory data duplication. Tachyon keeps only one copy of data in memory, tracks data lineage for fault tolerance, and enables fast sharing of data within and across frameworks and jobs. It provides a simple API and allows frameworks like Spark and MapReduce to access data reliably from memory without code changes.

Monitoring the Execution of 14K Tests: Methods Tend to Have One Path that Is ...Andre Hora
The literature has provided evidence that developers are likely to test some behaviors of the program and avoid other ones. Despite this observation, we still lack empirical evidence from real-world systems. In this paper, we propose to automatically identify the tested paths of a method as a way to detect the method’s behaviors. Then, we provide an empirical study to assess the tested paths quantitatively. We monitor the execution of 14,177 tests from 25 real-world Python systems and assess 11,425 tested paths from 2,357 methods. Overall, our empirical study shows that one tested path is prevalent and receives most of the calls, while others are significantly less executed. We find that the most frequently executed tested path of a method has 4x more calls than the second one. Based on these findings, we discuss practical implications for practitioners and researchers and future research directions.

When creating test cases, ideally, developers should test both the expected and unexpected behaviors of the program to catch more bugs and avoid regressions. However, the literature has provided evidence that developers are more likely to test expected behaviors than unexpected ones. In this paper, we propose PathSpotter, a tool to automatically identify tested paths and support the detection of missing tests. Based on PathSpotter, we provide an approach to guide us in detecting missing tests. To evaluate it, we submitted pull requests with test improvements to open-source projects. As a result, 6 out of 8 pull requests were accepted and merged in relevant systems, including CPython, Pylint, and Jupyter Client. These pull requests created/updated 32 tests and added 80 novel assertions covering untested cases. This indicates that our test improvement solution is well received by open-source projects.
