New Features

  • YARN Docker Runtime Support - YARN applications, such as Spark jobs, can now run in the context of a Docker container. This allows you to easily define dependencies in a Docker image without the need to install custom libraries on your Amazon EMR cluster. For more information, see Configure Docker Integration and Run Spark applications with Docker using Amazon EMR 6.0.0.

  • Hive LLAP Support - Hive now supports the LLAP execution mode for improved query performance. For more information, see Using Hive LLAP.

Changes, Enhancements, and Resolved Issues

  • Amazon Linux

    • Amazon Linux 2 is the operating system for the EMR 6.x release series.

    • systemd is used for service management instead of upstart used in Amazon Linux 1.

  • Java Development Kit (JDK)

    • Coretto JDK 8 is the default JDK for the EMR 6.x release series.

  • Scala

    • Scala 2.12 is used with Apache Spark and Apache Livy.

  • Python 3

    • Python 3 is now the default version of Python in EMR.

  • YARN node labels

    • Beginning with Amazon EMR 6.x release series, the YARN node labels feature is disabled by default. The application master processes can run on both core and task nodes by default. You can enable the YARN node labels feature by configuring following properties: yarn.node-labels.enabled and yarn.node-labels.am.default-node-label-expression. For more information, see Understanding Master, Core, and Task Nodes.

Known Issues

  • Spark interactive shell, including PySpark, SparkR, and spark-shell, does not support using Docker with additional libraries.

  • To use Python 3 with Amazon EMR version 6.0.0, you must add PATH to yarn.nodemanager.env-whitelist.

  • The Live Long and Process (LLAP) functionality is not supported when you use the AWS Glue Data Catalog as the metastore for Hive.

  • When using Amazon EMR 6.0.0 with Spark and Docker integration, you need to configure the instances in your cluster with the same instance type and the same amount of EBS volumes to avoid failure when submitting a Spark job with Docker runtime.

  • In Amazon EMR 6.0.0, HBase on Amazon S3 storage mode is impacted by the HBASE-24286. issue. HBase master cannot initialize when the cluster is created using existing S3 data.

6.0.0 Component Versions

The components that Amazon EMR installs with this release are listed below. Some are installed as part of big-data application packages. Others are unique to Amazon EMR and installed for system processes and features. These typically start with emr or aws. Big-data application packages in the most recent Amazon EMR release are usually the latest version found in the community. We make community releases available in Amazon EMR as quickly as possible.

Some components in Amazon EMR differ from community versions. These components have a version label in the form CommunityVersion-amzn-EmrVersion. The EmrVersion starts at 0. For example, if open source community component named myapp-component with version 2.2 has been modified three times for inclusion in different Amazon EMR release versions, its release version is listed as 2.2-amzn-2.
