Apache Spark - Amazon EMR

Apache Spark

Apache Spark is a distributed processing framework and programming model that helps you do machine learning, stream processing, or graph analytics with 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. It also 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.

You can install Spark on an Amazon EMR cluster along with other Hadoop applications, and it can also leverage the Amazon EMR file system (EMRFS) to directly access data in Amazon S3. Hive is also integrated with Spark so that you can use a HiveContext object to run Hive scripts using Spark. A Hive context is included in the spark-shell as sqlContext.

For an example tutorial on setting up an EMR cluster with Spark and analyzing a sample data set, see Tutorial: Getting started with Amazon EMR on the AWS News blog.

Important

Apache Spark version 2.3.1, available beginning with Amazon EMR release 5.16.0, addresses CVE-2018-8024 and CVE-2018-1334. We recommend that you migrate earlier versions of Spark to Spark version 2.3.1 or later.

The following table lists the version of Spark included in the latest release of the Amazon EMR 7.x series, along with the components that Amazon EMR installs with Spark.

Note

Amazon EMR release 6.8.0 comes with Apache Spark 3.3.0. This Spark release uses Apache Log4j 2 and the log4j2.properties file to configure Log4j in Spark processes. If you use Spark in the cluster or create EMR clusters with custom configuration parameters, and you want to upgrade to Amazon EMR release 6.8.0, you must migrate to the new spark-log4j2 configuration classification and key format for Apache Log4j 2. For more information, see Migrating from Apache Log4j 1.x to Log4j 2.x.

The following table lists the version of Spark included in the latest release of the Amazon EMR 5.x series, along with the components that Amazon EMR installs with Spark.
