Apache Spark (EMR 4.x Releases)

Apache Spark is a cluster framework and programming model that helps you do machine learning, stream processing, or graph analytics using Amazon EMR clusters. Similar to Apache Hadoop, Spark is an open-source, distributed processing system commonly used for big data workloads. However, Spark has several notable differences from Hadoop MapReduce. Spark has an optimized directed acyclic graph (DAG) execution engine and actively caches data in-memory, which can boost performance especially for certain algorithms and interactive queries.

Spark natively supports applications written in Scala, Python, and Java and includes several tightly integrated libraries for SQL (Spark SQL), machine learning (MLlib), stream processing (Spark Streaming), and graph processing (GraphX). These tools make it easier to leverage the Spark framework for a wide variety of use cases.

Spark can be installed alongside the other Hadoop applications available in Amazon EMR, and it can also leverage the EMR file system (EMRFS) to directly access data in Amazon S3. Hive is also integrated with Spark. So you can use a HiveContext object to run Hive scripts using Spark. A Hive context is included in the spark-shell as sqlContext.
