5.30.2 release notes

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.

Changes, Enhancements, and Resolved Issues

  • 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.

  • Newer Amazon EMR releases fix the issue with a lower "Max open files" limit on older AL2 in Amazon EMR. Amazon EMR releases 5.30.1, 5.30.2, 5.31.1, 5.32.1, 6.0.1, 6.1.1, 6.2.1, 5.33.0, 6.3.0 and later now include a permanent fix with a higher "Max open files" setting.

  • HTTPS is now enabled by default for Amazon Linux repositories. If you are using an Amazon S3 VPCE policy to restrict access to specific buckets, you must add the new Amazon Linux bucket ARN arn:aws:s3:::amazonlinux-2-repos-$region/* to your policy (replace $region with the region where the endpoint is). For more information, see this topic in the Amazon discussion forums. Announcement: Amazon Linux 2 now supports the ability to use HTTPS while connecting to package repositories .

Known issues

  • 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.

5.30.2 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.
