5.29.0 release notes

The following release notes include information for Amazon EMR release 5.29.0. Changes are relative to 5.28.1.

Initial release date: Jan 17, 2020

Upgrades

  • Upgraded AWS SDK for Java to version 1.11.682

  • Upgraded Hive to version 2.3.6

  • Upgraded Flink to version 1.9.1

  • Upgraded EmrFS to version 2.38.0

  • Upgraded EMR DynamoDB Connector to version 4.13.0

Changes, enhancements, and resolved issues

  • Spark

    • Spark performance optimizations.

  • EMRFS

    • Management Guide updates to emrfs-site.xml default settings for consistent view.

Known issues

  • Known issue in clusters with multiple primary nodes and Kerberos authentication

    If you run clusters with multiple primary nodes and Kerberos authentication in Amazon EMR releases 5.20.0 and later, you may encounter problems with cluster operations such as scale down or step submission, after the cluster has been running for some time. The time period depends on the Kerberos ticket validity period that you defined. The scale-down problem impacts both automatic scale-down and explicit scale down requests that you submitted. Additional cluster operations can also be impacted.

    Workaround:

    • SSH as hadoop user to the lead primary node of the EMR cluster with multiple primary nodes.

    • Run the following command to renew Kerberos ticket for hadoop user. 

      kinit -kt <keytab_file> <principal>

      Typically, the keytab file is located at /etc/hadoop.keytab and the principal is in the form of hadoop/<hostname>@<REALM>.

    Note

    This workaround will be effective for the time period the Kerberos ticket is valid. This duration is 10 hours by default, but can configured by your Kerberos settings. You must re-run the above command once the Kerberos ticket expires.

5.29.0 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.
