5.8.0 release notes

The following release notes include information for the Amazon EMR version 5.8.0 release. Changes are relative to the Amazon EMR 5.7.0 release.

Initial release date: August 10, 2017

Latest feature update: September 25, 2017

Upgrades

  • AWS SDK 1.11.160

  • Flink 1.3.1

  • Hive 2.3.0. For more information, see Release Notes on the Apache Hive site.

  • Spark 2.2.0. For more information, see Release Notes on the Apache Spark site.

New features

  • Added support for viewing application history (September 25, 2017). For more information, see Viewing Application History in the Amazon EMR Management Guide.

Changes, enhancements, and resolved issues
Known issues

  • Cluster launch fails when all applications are installed and the default Amazon EBS root volume size is not changed. As a workaround, use the aws emr create-cluster command from the AWS CLI and specify a larger --ebs-root-volume-size parameter.

  • Hive 2.3.0 sets hive.compute.query.using.stats=true by default. This causes queries to get data from existing statistics rather than directly from data, which could be confusing. For example, if you have a table with hive.compute.query.using.stats=true and upload new files to the table LOCATION, running a SELECT COUNT(*) query on the table returns the count from the statistics, rather than picking up the added rows.

    As a workaround, use the ANALYZE TABLE command to gather new statistics, or set hive.compute.query.using.stats=false. For more information, see Statistics in Hive in the Apache Hive documentation.

  • Spark—When using Spark, there is a file handler leak issue with the apppusher daemon, which can appear for a long-running Spark job after several hours or days. To fix the issue, connect to the primary node and type sudo /etc/init.d/apppusher stop. This stops that apppusher daemon, which Amazon EMR will restart automatically.

  • Application history

    • Historical data for dead Spark executors is not available.

    • Application history is not available for clusters that use a security configuration to enable in-flight encryption.

5.8.0 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.
