Apache HBase Internals you hoped you Never Needed to UnderstandJosh Elser
Covers numerous internal features, concepts, and implementations of Apache HBase. The focus will be driven from an operational standpoint, investigating each component enough to understand its role in Apache HBase and the generic problems that each are trying to solve. Topics will range from HBase’s RPC system to the new Procedure v2 framework, to filesystem and ZooKeeper use, to backup and replication features, to region assignment and row locks. Each topic will be covered at a high-level, attempting to distill the often complicated details down to the most salient information.
This document summarizes a presentation about Apache Phoenix, an open-source project that allows HBase to be queried with SQL. It discusses what Phoenix is, why tracing is important, and the features of a new tracing web app created for Phoenix, including listing traces, visualizing trace distributions and individual trace details. Programming challenges in creating the app and new issues filed are also summarized.

HBaseCon2017 Spark HBase Connector: Feature Rich and Efficient Access to HBas...HBaseCon
Both Spark and HBase are widely used, but how to use them together with high performance and simplicity is a very hard topic. Spark HBase Connector(SHC) provides feature rich and efficient access to HBase through Spark SQL. It bridges the gap between the simple HBase key value store and complex relational SQL queries and enables users to perform complex data analytics on top of HBase using Spark.
SHC implements the standard Spark data source APIs, and leverages the Spark catalyst engine for query optimization. To achieve high performance, SHC constructs the RDD from scratch instead of using the standard HadoopRDD. With the customized RDD, all critical techniques can be applied and fully implemented, such as partition pruning, column pruning, predicate pushdown and data locality. The design makes the maintenance very easy, while achieving a good tradeoff between performance and simplicity.
Also, SHC has supported Phoenix data as input to HBase in addition to Avro data. Defaulting to a simple native binary encoding seems susceptible to future changes and is a risk for users who write data from SHC into HBase. For example, with SHC going forward, backwards compatibility needs to be properly handled. So the default, SHC needs to support a more standard and well tested format like Phoenix.
In this talk, we will demo how SHC works, how to use SHC in secure/non-secure clusters, how SHC works with multi-HBase clusters, etc. This talk will also benefit people who use Spark and other data sources (besides HBase) as it inspires them with ideas of how to support high performance data source access at the Spark DataFrame level.

Apache Phoenix: Use Cases and New FeaturesHBaseCon
James Taylor (Salesforce) and Maryann Xue (Intel)
This talk with be broken into two parts: Phoenix use cases and new Phoenix features. Three use cases will be presented as lightning talks by individuals from 1) Sony about its social media NewsSuite app, 2) eHarmony on its matching service, and 3) Salesforce.com on its time-series metrics engine. Two new features will be discussed in detail by the engineers who developed them: ACID transactions in Phoenix through Apache Tephra. and cost-based query optimization through Apache Calcite. The focus will be on helping end users more easily develop scalable applications on top of Phoenix.
Kerberos is the system which underpins the vast majority of strong authentication across the Apache HBase/Hadoop application stack. Kerberos errors have brought many to their knees and it is often referred to as “black magic” or “the dark arts”; a long-standing joke that there are so few who understand how it works. This talk will cover the types of problems that Kerberos solves and doesn’t solve for HBase, decrypt some jargon on related libraries and technology that enable Kerberos authentication in HBase and Hadoop, and distill some basic takeaways designed to ease users in developing an application that can securely communicate with a “kerberized” HBase installation.
Hortonworks Technical Workshop: HBase and Apache Phoenix Hortonworks
This document provides an overview of Apache HBase and Apache Phoenix. It discusses how HBase is a scalable, non-relational database that can store large volumes of data across commodity servers. Phoenix provides a SQL interface for HBase, allowing users to interact with HBase data using familiar SQL queries and functions. The document outlines new features in Phoenix for HDP 2.2, including improved support for secondary indexes and basic window functions.
Major advancements in Apache Hive towards full support of SQL compliance include:
1) Adding support for SQL2011 keywords and reserved keywords to reduce parser ambiguity issues.
2) Adding support for primary keys and foreign keys to improve query optimization, specifically cardinality estimation for joins.
3) Implementing set operations like INTERSECT and EXCEPT by rewriting them using techniques like grouping, aggregation, and user-defined table functions.
The document summarizes Apache Phoenix and its past, present, and future as a SQL interface for HBase. It describes Phoenix's architecture and key features like secondary indexes, joins, aggregations, and transactions. Recent releases added functional indexes, the Phoenix Query Server, and initial transaction support. Future plans include improvements to local indexes, integration with Calcite and Hive, and adding JSON and other SQL features. The document aims to provide an overview of Phoenix's capabilities and roadmap for building a full-featured SQL layer over HBase.
Design Patterns For Real Time Streaming Data AnalyticsDataWorks Summit
This document provides an overview of design patterns for real-time streaming data analytics. It discusses architectural patterns like real-time streaming and lambda architecture. It also covers functional patterns like stream joins and top N trends. Additionally, it describes data management patterns such as external lookup, responsive shuffling, and handling out-of-sequence events. The presentation includes examples and benefits of these patterns for building scalable streaming applications.
Using Apache Hadoop and related technologies as a data warehouse has been an area of interest since the early days of Hadoop. In recent years Hive has made great strides towards enabling data warehousing by expanding its SQL coverage, adding transactions, and enabling sub-second queries with LLAP. But data warehousing requires more than a full powered SQL engine. Security, governance, data movement, workload management, monitoring, and user tools are required as well. These functions are being addressed by other Apache projects such as Ranger, Atlas, Falcon, Ambari, and Zeppelin. This talk will examine how these projects can be assembled to build a data warehousing solution. It will also discuss features and performance work going on in Hive and the other projects that will enable more data warehousing use cases. These include use cases like data ingestion using merge, support for OLAP cubing queries via Hive’s integration with Druid, expanded SQL coverage, replication of data between data warehouses, advanced access control options, data discovery, and user tools to manage, monitor, and query the warehouse.
This talk will give an overview of two exciting releases for Apache HBase 2.0 and Phoenix 5.0. HBase provides a NoSQL column store on Hadoop for random, real-time read/write workloads.

Harnessing Wild and Untamed (Publicly Available) Data for the Cost efficient ...weiwchu
We recently discovered that models trained with large-scale speech datasets sourced from the web could achieve superior accuracy and potentially lower cost than traditionally human-labeled or simulated speech datasets. We developed a customizable AI-driven data labeling system. It infers word-level transcriptions with confidence scores, enabling supervised ASR training. It also robustly generates phone-level timestamps even in the presence of transcription or recognition errors, facilitating the training of TTS models. Moreover, It automatically assigns labels such as scenario, accent, language, and topic tags to the data, enabling the selection of task-specific data for training a model tailored to that particular task. We assessed the effectiveness of the datasets by fine-tuning open-source large speech models such as Whisper and SeamlessM4T and analyzing the resulting metrics. In addition to openly-available data, our data handling system can also be tailored to provide reliable labels for proprietary data from certain vertical domains. This customization enables supervised training of domain-specific models without the need for human labelers, eliminating data breach risks and significantly reducing data labeling cost.
