5.34.0 release notes

The following release notes include information for Amazon EMR release 5.34.0. Changes are relative to 5.33.1.

Initial release date: January 20, 2022

Updated release date: March 21, 2022

New Features

  • [Managed scaling] Spark shuffle data managed scaling optimization - For Amazon EMR versions 5.34.0 and later, and EMR versions 6.4.0 and later, managed scaling is now Spark shuffle data aware (data that Spark redistributes across partitions to perform specific operations). For more information on shuffle operations, see Using EMR managed scaling in Amazon EMR in the Amazon EMR Management Guide and Spark Programming Guide.

  • [Hudi] Improvements to simplify Hudi configuration. Disabled optimistic concurrency control by default.

Changes, Enhancements, and Resolved Issues

  • This is a release to fix issues with Amazon EMR Scaling when it fails to scale up/scale down a cluster successfully or causes application failures.

  • Previously, manual restart of the resource manager on a multi-master cluster caused Amazon EMR on-cluster daemons, like Zookeeper, to reload all previously decommissioned or lost nodes in the Zookeeper znode file. This caused default limits to be exceeded in certain situations. Amazon EMR now removes the decommissioned or lost node records older than one hour from the Zookeeper file and the internal limits have been increased.

  • Fixed an issue where scaling requests failed for a large, highly utilized cluster when Amazon EMR on-cluster daemons were running health checking activities, such as gathering YARN node state and HDFS node state. This was happening because on-cluster daemons were not able to communicate the health status data of a node to internal Amazon EMR components.

  • Improved EMR on-cluster daemons to correctly track the node states when IP addresses are reused to improve reliability during scaling operations.

  • SPARK-29683. Fixed an issue where job failures occurred during cluster scale-down as Spark was assuming all available nodes were deny-listed.

  • YARN-9011. Fixed an issue where job failures occurred due to a race condition in YARN decommissioning when cluster tried to scale up or down.

  • Fixed issue with step or job failures during cluster scaling by ensuring that the node states are always consistent between the Amazon EMR on-cluster daemons and YARN/HDFS.

  • Fixed an issue where cluster operations such as scale down and step submission failed for Amazon EMR clusters enabled with Kerberos authentication. This was because the Amazon EMR on-cluster daemon did not renew the Kerberos ticket, which is required to securely communicate with HDFS/YARN running on the primary node.

  • Zeppelin upgraded to version 0.10.0.

  • Livy Fix - upgraded to 0.7.1

  • Spark performance improvement - heterogeneous executors are disabled when certain Spark configuration values are overridden in EMR 5.34.0.

  • WebHDFS and HttpFS server are disabled by default. You can re-enable WebHDFS using the Hadoop configuration, dfs.webhdfs.enabled. HttpFS server can be started by using sudo systemctl start hadoop-httpfs.

Known Issues

  • The Amazon EMR Notebooks feature used with Livy user impersonation does not work because HttpFS is disabled by default. In this case, the EMR notebook cannot connect to the cluster that has Livy impersonation enabled. The workaround is to start HttpFS server before connecting the EMR notebook to the cluster using sudo systemctl start hadoop-httpfs.

  • Hue queries do not work in Amazon EMR 6.4.0 because Apache Hadoop HttpFS server is disabled by default. To use Hue on Amazon EMR 6.4.0, either manually start HttpFS server on the Amazon EMR primary node using sudo systemctl start hadoop-httpfs, or use an Amazon EMR step.

  • The Amazon EMR Notebooks feature used with Livy user impersonation does not work because HttpFS is disabled by default. In this case, the EMR notebook cannot connect to the cluster that has Livy impersonation enabled. The workaround is to start HttpFS server before connecting the EMR notebook to the cluster using sudo systemctl start hadoop-httpfs.

  • When you use Spark with Hive partition location formatting to read data in Amazon S3, and you run Spark on Amazon EMR releases 5.30.0 to 5.36.0, and 6.2.0 to 6.9.0, you might encounter an issue that prevents your cluster from reading data correctly. This can happen if your partitions have all of the following characteristics:

    • Two or more partitions are scanned from the same table.

    • At least one partition directory path is a prefix of at least one other partition directory path, for example, s3://bucket/table/p=a is a prefix of s3://bucket/table/p=a b.

    • The first character that follows the prefix in the other partition directory has a UTF-8 value that’s less than than the / character (U+002F). For example, the space character (U+0020) that occurs between a and b in s3://bucket/table/p=a b falls into this category. Note that there are 14 other non-control characters: !"#$%&‘()*+,-. For more information, see UTF-8 encoding table and Unicode characters.

    As a workaround to this issue, set the spark.sql.sources.fastS3PartitionDiscovery.enabled configuration to false in the spark-defaults classification.

5.34.0 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.

5.34.0 configuration classifications

Configuration classifications allow you to customize applications. These often correspond to a configuration XML file for the application, such as hive-site.xml. For more information, see Configure applications.

Reconfiguration actions occur when you specify a configuration for instance groups in a running cluster. Amazon EMR only initiates reconfiguration actions for the classifications that you modify. For more information, see Reconfigure an instance group in a running cluster.
