Introduction to Apache Spark

Samy Dindane

Apache Spark is a fast distributed data processing engine that runs in memory. It can be used with Java, Scala, Python and R. Spark uses resilient distributed datasets (RDDs) as its main data structure. RDDs are immutable and partitioned collections of elements that allow transformations like map and filter. Spark is 10-100x faster than Hadoop for iterative algorithms and can be used for tasks like ETL, machine learning, and streaming.

Akka in Production - ScalaDays 2015

Evan Chan

Everyone in the Scala world is using or looking into using Akka for low-latency, scalable, distributed or concurrent systems. I'd like to share my story of developing and productionizing multiple Akka apps, including low-latency ingestion and real-time processing systems, and Spark-based applications. When does one use actors vs futures? Can we use Akka with, or in place of, Storm? How did we set up instrumentation and monitoring in production? How does one use VisualVM to debug Akka apps in production? What happens if the mailbox gets full? What is our Akka stack like? I will share best practices for building Akka and Scala apps, pitfalls and things we'd like to avoid, and a vision of where we would like to go for ideal Akka monitoring, instrumentation, and debugging facilities. Plus backpressure and at-least-once processing.

Robert "Chip" Senkbeil

NOTE: This was converted to Powerpoint from Keynote. Slideshare does not play the embedded videos. You can download the powerpoint from slideshare and import it into keynote. The videos should work in the keynote. Abstract: In this presentation, we will describe the "Spark Kernel" which enables applications, such as end-user facing and interactive applications, to interface with Spark clusters. It provides a gateway to define and run Spark tasks and to collect results from a cluster without the friction associated with shipping jars and reading results from peripheral systems. Using the Spark Kernel as a proxy, applications can be hosted remotely from Spark.

Sqoop on Spark for Data Ingestion-(Veena Basavaraj and Vinoth Chandar, Uber)

Spark Summit

This document discusses running Sqoop jobs on Apache Spark for faster data ingestion into Hadoop. The authors describe how Sqoop jobs can be executed as Spark jobs by leveraging Spark's faster execution engine compared to MapReduce. They demonstrate running a Sqoop job to ingest data from MySQL to HDFS using Spark and show it is faster than using MapReduce. Some challenges encountered are managing dependencies and job submission, but overall it allows leveraging Sqoop's connectors within Spark's distributed processing framework. Next steps include exploring alternative job submission methods in Spark and adding transformation capabilities to Sqoop connectors.

Cepoi Eugen

This document summarizes Viadeo's use of Apache Spark. It discusses how Spark is used to build models for job offer click prediction and member segmentation. Spark jobs process event log data from HDFS and HBase to cluster job titles, build relationship graphs, compute input variables for regression models, and evaluate segments. The models improve click-through rates and allow flexible, fast member targeting. Future work includes indexing segmentations and exposing them for analytics and online campaign building.

Spark on YARN

Adarsh Pannu

Spark supports four cluster managers: Local, Standalone, YARN, and Mesos. YARN is highly recommended for production use. When running Spark on YARN, careful tuning of configuration settings like the number of executors, executor memory and cores, and dynamic allocation is important to optimize performance and resource utilization. Configuring queues also allows separating different applications by priority and resource needs.

Queries can be run on Spark SQL contexts configured to use data from HDFS, Cassandra, Parquet files on HDFS or Tachyon. 3) The architecture allows Jaws to scale on standalone, Mesos, or YARN clusters by distributing queries across multiple worker nodes, and supports canceling running queries.

The Pushdown of Everything by Stephan Kessler and Santiago Mola

Spark Summit

Stephan Kessler and Santiago Mola presented SAP HANA Vora, which extends Spark SQL's data sources API to allow "pushing down" more of a SQL query's logical plan to the data source for execution. This "Pushdown of Everything" approach leverages data sources' capabilities to process less data and optimize query execution. They described how data sources can implement interfaces like TableScan, PrunedScan, and the new CatalystSource interface to support pushing down projections, filters, and more complex queries respectively. While this approach has advantages in performance, challenges include the complexity of implementing CatalystSource and ensuring compatibility across Spark versions. Future work aims to improve the API and provide utilities to simplify implementation.

Chromosomes, chromatin and cellular cycle

Kamila Varon

Cellular cycle is important in cell growth, development, and death. Studying this area helps understand diseases associated with these processes. Researchers identified the cell of origin in leukemia cases using mouse experiments expressing MLL-AF2. They analyzed different cell states in mice and a control group. Further studies may open new avenues for early cancer diagnosis and treatment. A gene mutation was found to cause brittle bone disease and other connective tissue issues in two families, showing one gene can cause multiple diseases. These studies increase understanding of known diseases and could reveal unknown ones, expanding human knowledge.

1) Between 2000-2012 in Australia, 98 people died from interactions with horses due to bites, strikes, kicks or falls. New safety guidelines aim to reduce these risks. 2) The safety code was created after the death of a woman on a horse riding course. It defines inexperienced riders as those new to a situation, not just new to horses. Clubs must ensure safety for all. 3) Event organizers have a duty of care for participant safety. They must identify and address hazards, clearly communicate policies, and ensure responsibilities are understood by all. Culture and assumptions can affect safety and must be addressed carefully.

Droplet size and velocity characteristics of agricultural sprays

Gajanan Bele

This document summarizes research on the droplet size and velocity characteristics of different agricultural spray nozzles. Droplet size and velocity are important factors that influence spray application efficiency. The study tested various nozzle types and operating pressures. It was found that smaller nozzles and higher pressures produced finer droplet sizes. Larger droplets had higher velocities, while smaller droplets had lower velocities. Nozzle type also impacted velocities, with flat fan nozzles producing the highest velocities. Understanding the relationship between droplet size, velocity and nozzle parameters can help optimize pesticide application and deposition.

This talk, that I gave at the Chicago Java Users Group (CJUG) on June 8th 2017, is mainly focusing on Kafka Streams, a lightweight open source Java library for building stream processing applications on top of Kafka using Kafka topics as input/output. You will learn more about the following: 1. Apache Kafka: a Streaming Data Platform 2. Overview of Kafka Streams: Before Kafka Streams? What is Kafka Streams? Why Kafka Streams? What are Kafka Streams key concepts? Kafka Streams APIs and code examples? 3. Writing, deploying and running your first Kafka Streams application 4. Code and Demo of an end-to-end Kafka-based Streaming Data Application 5. Where to go from here?

Using the SDACK Architecture to Build a Big Data Product

Evans Ye

You definitely have heard about the SMACK architecture, which stands for Spark, Mesos, Akka, Cassandra, and Kafka. It’s especially suitable for building a lambda architecture system. But what is SDACK? Apparently it’s very much similar to SMACK except the “D" stands for Docker. While SMACK is an enterprise scale, multi-tanent supported solution, the SDACK architecture is particularly suitable for building a data product. In this talk, I’ll talk about the advantages of the SDACK architecture, and how TrendMicro uses the SDACK architecture to build an anomaly detection data product. The talk will cover: 1) The architecture we designed based on SDACK to support both batch and streaming workload. 2) The data pipeline built based on Akka Stream which is flexible, scalable, and able to do self-healing. 3) The Cassandra data model designed to support time series data writes and reads.
