5.12.0 release notes

The following release notes include information for the Amazon EMR release 5.12.0. Changes are relative to 5.11.1.

Upgrades
Changes, enhancements, and resolved issues

  • Hadoop

    • The yarn.resourcemanager.decommissioning.timeout property has changed to yarn.resourcemanager.nodemanager-graceful-decommission-timeout-secs. You can use this property to customize cluster scale-down. For more information, see Cluster Scale-Down in the Amazon EMR Management Guide.

    • The Hadoop CLI added the -d option to the cp (copy) command, which specifies direct copy. You can use this to avoid creating an intermediary .COPYING file, which makes copying data between Amazon S3 faster. For more information, see HADOOP-12384.

  • Pig

    • Added the pig-env configuration classification, which simplifies the configuration of Pig environment properties. For more information, see Configure applications.

  • Presto

    • Added the presto-connector-redshift configuration classification, which you can use to configure values in the Presto redshift.properties configuration file. For more information, see Redshift Connector in Presto documentation, and Configure applications.

    • Presto support for EMRFS has been added and is the default configuration. Earlier Amazon EMR releases used PrestoS3FileSystem, which was the only option. For more information, see EMRFS and PrestoS3FileSystem configuration.

      Note

      If you query underlying data in Amazon S3 with Amazon EMR version 5.12.0, Presto errors can occur. This is because Presto fails to pick up configuration classification values from emrfs-site.xml. As a workaround, create an emrfs subdirectory under usr/lib/presto/plugin/hive-hadoop2/ and create a symlink in usr/lib/presto/plugin/hive-hadoop2/emrfs to the existing /usr/share/aws/emr/emrfs/conf/emrfs-site.xml file. Then restart the presto-server process (sudo presto-server stop followed by sudo presto-server start).

  • Spark

Known issues

  • MXNet does not include OpenCV libraries.

  • SparkR is not available for clusters created using a custom AMI because R is not installed by default on cluster nodes.

5.12.0 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 releases, its release version is listed as 2.2-amzn-2.
