6.8.0 release notes

The following release notes include information for Amazon EMR release 6.8.0. Changes are relative to 6.7.0.

New Features

  • Amazon EMR steps feature now supports Apache Livy endpoint and JDBC/ODBC clients. For more information, see Configure runtime roles for Amazon EMR steps.

  • Amazon EMR release 6.8.0 comes with Apache HBase release 2.4.12. With this HBase release, you can both archive and delete your HBase tables. The Amazon S3 archive process renames all table files to the archive directory. This can be a costly and lengthy process. Now, you can skip the archive process and quickly drop and delete large tables. For more information, see Using the HBase shell.

Known Issues

  • Hadoop 3.3.3 introduced a change in YARN (YARN-9608) that keeps nodes where containers ran in a decommissioning state until the application completes. This change ensures that local data such as shuffle data doesn't get lost, and you don' need to re-run the job. In Amazon EMR 6.8.0 and 6.9.0, this approach might also lead to underutilization of resources on clusters with or without managed scaling enabled.

    With Amazon EMR 6.10.0, there's a workaround for this issue to set the value of yarn.resourcemanager.decommissioning-nodes-watcher.wait-for-applications to false in yarn-site.xml. In Amazon EMR releases 6.11.0 and higher as well as 6.8.1, 6.9.1, and 6.10.1, the config is set to false by default to resolve this issue.

Changes, Enhancements, and Resolved Issues

  • When Amazon EMR release 6.5.0, 6.6.0, or 6.7.0 read Apache Phoenix tables through the Apache Spark shell, Amazon EMR produced a NoSuchMethodError. Amazon EMR release 6.8.0 fixes this issue.

  • Amazon EMR release 6.8.0 comes with Apache Hudi 0.11.1; however, Amazon EMR 6.8.0 clusters are also compatible with the open-source hudi-spark3.3-bundle_2.12 from Hudi 0.12.0.

  • Amazon EMR release 6.8.0 comes with Apache Spark 3.3.0. This Spark release uses Apache Log4j 2 and the log4j2.properties file to configure Log4j in Spark processes. If you use Spark in the cluster or create EMR clusters with custom configuration parameters, and you want to upgrade to Amazon EMR release 6.8.0, you must migrate to the new spark-log4j2 configuration classification and key format for Apache Log4j 2. For more information, see Migrating from Apache Log4j 1.x to Log4j 2.x.

  • When you launch a cluster with the latest patch release of Amazon EMR 5.36 or higher, 6.6 or higher, or 7.0 or higher, Amazon EMR uses the latest Amazon Linux 2023 or Amazon Linux 2 release for the default Amazon EMR AMI. For more information, see Using the default Amazon Linux AMI for Amazon EMR.

    Note

    This release no longer gets automatic AMI updates since it has been succeeded by 1 more more patch releases. The patch release is denoted by the number after the second decimal point (6.8.1). To see if you're using the latest patch release, check the available releases in the Release Guide, or check the Amazon EMR release dropdown when you create a cluster in the console, or use the ListReleaseLabels API or list-release-labels CLI action. To get updates about new releases, subscribe to the RSS feed on the What's new? page.

Known Issues

  • When you use the DynamoDB connector with Spark on Amazon EMR versions 6.6.0, 6.7.0, and 6.8.0, all reads from your table return an empty result, even though the input split references non-empty data. This is because Spark 3.2.0 sets spark.hadoopRDD.ignoreEmptySplits to true by default. As a workaround, explicitly set spark.hadoopRDD.ignoreEmptySplits to false. Amazon EMR release 6.9.0 fixes this issue.

  • 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.

  • With Amazon EMR releases 5.36.0 and 6.6.0 through 6.9.0, SecretAgent and RecordServer service components may experience log data loss due to an incorrect file name pattern configuration in Log4j2 properties. The incorrect configuration causes the components to generate only one log file per day. When the rotation strategy occurs, it overwrites the existing file instead of generating a new log file as expected. As a workaround, use a bootstrap action to generate log files each hour and append an auto-increment integer in the file name to handle the rotation.

    For Amazon EMR 6.6.0 through 6.9.0 releases, use the following bootstrap action when you launch a cluster. 

    ‑‑bootstrap‑actions "Path=s3://emr-data-access-control-us-east-1/customer-bootstrap-actions/log-rotation-emr-6x/replace-puppet.sh,Args=[]"

    For Amazon EMR 5.36.0, use the following bootstrap action when you launch a cluster.

    ‑‑bootstrap‑actions "Path=s3://emr-data-access-control-us-east-1/customer-bootstrap-actions/log-rotation-emr-5x/replace-puppet.sh,Args=[]"

For more information on the release timeline, see the change log.

6.8.0 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.

6.8.0 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.
