Amazon EMR 5.x Release Versions

Each tab below lists application versions, release notes, component versions, and configuration classifications available in each Amazon EMR 5.x release version.

For a comprehensive diagram of application versions in every release, see Application Versions in Amazon EMR 5.x Releases (PNG).

When you launch a cluster, you can choose from multiple release versions of Amazon EMR. This allows you to test and use application versions that fit your compatibility requirements. You specify the release version using the release label. Release labels are in the form emr-x.x.x. For example, emr-5.23.0.

New Amazon EMR release versions are made available in different regions over a period of several days, beginning with the first region on the initial release date. The latest release version may not be available in your region during this period.

5.23.0 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 need changes from community versions for Amazon EMR. These components have a version label in the form CommunityVersion-amzn-EmrVersion. For example, if a big-data community component named myapp-component of version 2.2 has been modified three times for inclusion in different Amazon EMR release versions, its release version is listed as 2.2-amzn-3.

5.22.0 Application Versions

The following applications are supported in this release: Flink, Ganglia, Hadoop, HBase, HCatalog, Hive, Hue, JupyterHub, Livy, Mahout, MXNet, Oozie, Phoenix, Pig, Presto, Spark, Sqoop, TensorFlow, Tez, Zeppelin, and ZooKeeper.

The diagram below depicts the application versions available in this release of Amazon EMR and the application versions in the preceding four Amazon EMR releases.

• Application Versions for 4.x Series Amazon EMR Releases (PNG)

5.22.0 Release Notes

The following release notes include information for Amazon EMR release version 5.22.0. Changes are relative to 5.21.0.

Initial release date: March 20, 2019

Upgrades

• Flink 1.7.1

• HBase 1.4.9

• Oozie 5.1.0

• Phoenix 4.14.1

• Zeppelin 0.8.1

• Connectors and drivers:

  • DynamoDB Connector 4.8.0

  • MariaDB Connector 2.2.6

  • Amazon Redshift JDBC Driver 1.2.20.1043

New Features

• Modified the default EBS configuration for EC2 instance types with EBS-only storage. When you create a cluster using Amazon EMR release version 5.22.0 and later, the default amount of EBS storage increases based on the size of the instance. In addition, we split increased storage across multiple volumes, giving increased IOPS performance. If you want to use a different EBS instance storage configuration, you can specify it when you create an EMR cluster or add nodes to an existing cluster. For more information about the amount of storage and number of volumes allocated by default for each instance type, see Default EBS Storage for Instances in the Amazon EMR Management Guide.

Changes, Enhancements, and Resolved Issues

• Spark

  • Introduced a new configuration property for Spark on YARN, spark.yarn.executor.memoryOverheadFactor. The value of this property is a scale factor that sets the value of memory overhead to a percentage of executor memory, with a minimum of 384 MB. If memory overhead is set explicitly using spark.yarn.executor.memoryOverhead, this property has no effect. The default value is 0.1875, representing 18.75%. This default for Amazon EMR leaves more space in YARN containers for executor memory overhead than the 10% default set internally by Spark. The Amazon EMR default of 18.75% empirically showed fewer memory-related failures in TPC-DS benchmarks.

  • Backported SPARK-26316 to improve performance.

5.21.0 Application Versions

The following applications are supported in this release: Flink, Ganglia, Hadoop, HBase, HCatalog, Hive, Hue, JupyterHub, Livy, Mahout, MXNet, Oozie, Phoenix, Pig, Presto, Spark, Sqoop, TensorFlow, Tez, Zeppelin, and ZooKeeper.

The diagram below depicts the application versions available in this release of Amazon EMR and the application versions in the preceding four Amazon EMR releases.

For a comprehensive history of application versions for each release of Amazon EMR, see the following diagrams:

• Application Versions for 5.x Series Amazon EMR Releases (PNG)

• Application Versions for 4.x Series Amazon EMR Releases (PNG)

5.21.0 Release Notes

The following release notes include information for Amazon EMR release version 5.21.0. Changes are relative to 5.20.0.

Initial release date: February 18, 2019

Last updated date: April 3, 2019

Upgrades

• Flink 1.7.0

• Presto 0.215

• AWS SDK for Java 1.11.479

New Features

• (April 3, 2019) With Amazon EMR version 5.21.0 and later, you can override cluster configurations and specify additional configuration classifications for each instance group in a running cluster. You do this by using the Amazon EMR console, the AWS Command Line Interface (AWS CLI), or the AWS SDK. For more information, see Supplying a Configuration for an Instance Group in a Running Cluster.

Changes, Enhancements, and Resolved Issues

• Zeppelin

  • Backported ZEPPELIN-3878.

Known Issues

• Tez

  • This issue was fixed in Amazon EMR 5.22.0.

    When you connect to the Tez UI at http://MasterDNS:8080/tez-ui through an SSH connection to the cluster master node, the error "Adapter operation failed - Timeline server (ATS) is out of reach. Either it is down, or CORS is not enabled" appears, or tasks unexpectedly show N/A.

    This is caused by the Tez UI making requests to the YARN Timeline Server using localhost rather than the host name of the master node. As a workaround, a script is available to run as a bootstrap action or step. The script updates the host name in the Tez configs.env file. For more information and the location of the script, see the Bootstrap Instructions.

5.21.0 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 need changes from community versions for Amazon EMR. These components have a version label in the form CommunityVersion-amzn-EmrVersion. For example, if a big-data community component named myapp-component of version 2.2 has been modified three times for inclusion in different Amazon EMR release versions, its release version is listed as 2.2-amzn-3.

5.20.0 Release Notes

The following release notes include information for Amazon EMR release version 5.20.0. Changes are relative to 5.19.0.

Initial release date: December 18, 2018

Last updated date: January 22, 2019

Upgrades

• Flink 1.6.2

• HBase 1.4.8

• Hive 2.3.4

• Hue 4.3.0

• MXNet 1.3.1

• Presto 0.214

• Spark 2.4.0

• TensorFlow 1.12.0

• Tez 0.9.1

• AWS SDK for Java 1.11.461

New Features

• (January 22, 2019) Kerberos in Amazon EMR has been improved to support authenticating principals from an external KDC. This centralizes principal management because multiple clusters can share a single, external KDC. In addition, the external KDC can have a cross-realm trust with an Active Directory domain. This allows all clusters to authenticate principals from Active Directory. For more information, see Use Kerberos Authentication in the Amazon EMR Management Guide.

Changes, Enhancements, and Resolved Issues

• Default Amazon Linux AMI for Amazon EMR

  • Python3 package was upgraded from python 3.4 to 3.6.

• The EMRFS S3-optimized committer

  • The EMRFS S3-optimized committer is now enabled by default, which improves write performance. For more information, see Using the EMRFS S3-optimized Committer.

• Hive

  • Backported HIVE-16686.

• Glue with Spark and Hive

  • In EMR 5.20.0 or later, parallel partition pruning is enabled automatically for Spark and Hive when AWS Glue Data Catalog is used as the metastore. This change significantly reduces query planning time by executing multiple requests in parallel to retrieve partitions. The total number of segments that can be executed concurrently range between 1 and 10. The default value is 5, which is a recommended setting. You can change it by specifying the property aws.glue.partition.num.segments in hive-site configuration classification. If throttling occurs, you can turn off the feature by changing the value to 1. For more information, see AWS Glue Segment Structure.

Known Issues

• Tez

  • This issue was fixed in Amazon EMR 5.22.0.

    When you connect to the Tez UI at http://MasterDNS:8080/tez-ui through an SSH connection to the cluster master node, the error "Adapter operation failed - Timeline server (ATS) is out of reach. Either it is down, or CORS is not enabled" appears, or tasks unexpectedly show N/A.

    This is caused by the Tez UI making requests to the YARN Timeline Server using localhost rather than the host name of the master node. As a workaround, a script is available to run as a bootstrap action or step. The script updates the host name in the Tez configs.env file. For more information and the location of the script, see the Bootstrap Instructions.

5.19.0 Release Notes

The following release notes include information for Amazon EMR release version 5.19.0. Changes are relative to 5.18.0.

Initial release date: November 7, 2018

Last updated date: November 19, 2018

Upgrades

• Hadoop 2.8.5

• Flink 1.6.1

• JupyterHub 0.9.4

• MXNet 1.3.0

• Presto 0.212

• TensorFlow 1.11.0

• Zookeeper 3.4.13

• AWS SDK for Java 1.11.433

New Features

• (Nov. 19, 2018) EMR Notebooks is a managed environment based on Jupyter Notebook. It supports Spark magic kernels for PySpark, Spark SQL, Spark R, and Scala. EMR Notebooks can be used with clusters created using Amazon EMR release version 5.18.0 and later. For more information, see Using EMR Notebooks in the Amazon EMR Management Guide.

• The EMRFS S3-optimized committer is available when writing Parquet files using Spark and EMRFS. This committer improves write performance. For more information, see Using the EMRFS S3-optimized Committer.

Changes, Enhancements, and Resolved Issues

• YARN

  • Modified the logic that limits the application master process to running on core nodes. This functionality now uses the YARN node labels feature and properties in the yarn-site and capacity-scheduler configuration classifications. For information, see https://docs.aws.amazon.com/emr/latest/ManagementGuide/emr-plan-instances-guidelines.html#emr-plan-spot-YARN.

• Default Amazon Linux AMI for Amazon EMR

  • ruby18, php56, and gcc48 are no longer installed by default. These can be installed if desired using yum.

  • The aws-java-sdk ruby gem is no longer installed by default. It can be installed using gem install aws-java-sdk, if desired. Specific components can also be installed. For example, gem install aws-java-sdk-s3.

Known Issues

• EMR Notebooks—In some circumstances, with multiple notebook editors open, the notebook editor may appear unable to connect to the cluster. If this happens, clear browser cookies and then reopen notebook editors.

5.19.0 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 need changes from community versions for Amazon EMR. These components have a version label in the form CommunityVersion-amzn-EmrVersion. For example, if a big-data community component named myapp-component of version 2.2 has been modified three times for inclusion in different Amazon EMR release versions, its release version is listed as 2.2-amzn-3.

5.17.0 Application Versions

The following applications are supported in this release: Flink, Ganglia, Hadoop, HBase, HCatalog, Hive, Hue, JupyterHub, Livy, Mahout, MXNet, Oozie, Phoenix, Pig, Presto, Spark, Sqoop, TensorFlow, Tez, Zeppelin, and ZooKeeper.

The diagram below depicts the application versions available in this release of Amazon EMR and the application versions in the preceding four Amazon EMR releases.

For a comprehensive history of application versions for each release of Amazon EMR, see the following diagrams:

• Application Versions for 5.x Series Amazon EMR Releases (PNG)

• Application Versions for 4.x Series Amazon EMR Releases (PNG)

5.17.0 Release Notes

The following release notes include information for Amazon EMR release version 5.17.0. Changes are relative to 5.16.0.

Initial release date: August 30, 2018

Upgrades

• Flink 1.5.2

• HBase 1.4.6

• Presto 0.206

New Features

• Added support for Tensorflow. For more information, see TensorFlow.

Changes, Enhancements, and Resolved Issues

• JupyterHub

  • Added support for notebook persistence in Amazon S3. For more information, see Configuring Persistence for Notebooks in Amazon S3.

• Spark

  • Added support for S3 Select. For more information, see Using S3 Select with Spark to Improve Query Performance.

Known Issues

• When you create a kerberized cluster with Livy installed, Livy fails with an error that simple authentication is not enabled. Rebooting the Livy server resolves the issue. As a workaround, add a step during cluster creation that runs sudo restart livy-server on the master node.

• If you use a custom Amazon Linux AMI based on an Amazon Linux AMI with a creation date of 2018-08-11, the Oozie server fails to start. If you use Oozie, create a custom AMI based on an Amazon Linux AMI ID with a different creation date. You can use the following AWS CLI command to return a list of Image IDs for all HVM Amazon Linux AMIs with a 2018.03 version, along with the release date, so that you can choose an appropriate Amazon Linux AMI as your base. Replace MyRegion with your region identifier, such as us-west-2.

  aws ec2 --region MyRegion describe-images --owner amazon --query 'Images[?Name!=`null`]|[?starts_with(Name, `amzn-ami-hvm-2018.03`) == `true`].[CreationDate,ImageId,Name]' --output text | sort -rk1
  

5.17.0 Component Versions

The following applications are supported in this release: Flink, Ganglia, Hadoop, HBase, HCatalog, Hive, Hue, JupyterHub, Livy, Mahout, MXNet, Oozie, Phoenix, Pig, Presto, Spark, Sqoop, Tez, Zeppelin, and ZooKeeper.

5.14.0 Release Notes

The following release notes include information for Amazon EMR release version 5.14.0. Changes are relative to 5.13.0.

Initial release date: June 4, 2018

Upgrades

• Upgraded Apache Flink to 1.4.2

• Upgraded Apache MXnet to 1.1.0

• Upgraded Apache Sqoop to 1.4.7

New Features

• Added JupyterHub support. For more information, see JupyterHub.

Changes, Enhancements, and Resolved Issues

• EMRFS

  • The userAgent string in requests to Amazon S3 has been updated to contain the user and group information of the invoking principal. This can be used with AWS CloudTrail logs for more comprehensive request tracking.

• HBase

  • Included HBASE-20447, which addresses an issue that could cause cache issues, especially with split regions.

• MXnet

  • Added OpenCV libraries.

• Spark

  • When Spark writes Parquet files to an Amazon S3 location using EMRFS, the FileOutputCommitter algorithm has been updated to use version 2 instead of version 1. This reduces the number of renames, which improves application performance. This change does not affect:

    • Applications other than Spark.

    • Applications that write to other file systems, such as HDFS (which still use version 1 of FileOutputCommitter).

    • Applications that use other output formats, such as text or csv, that already use EMRFS direct write.

Known Issues

• JupyterHub

  • Using configuration classifications to set up JupyterHub and individual Jupyter notebooks when you create a cluster is not supported. Edit the jupyterhub_config.py file and jupyter_notebook_config.py files for each user manually. For more information, see Configuring JupyterHub.

  • JupyterHub fails to start on clusters within a private subnet, failing with the message Error: ENOENT: no such file or directory, open '/etc/jupyter/conf/server.crt' . This is caused by an error in the script that generates self-signed certificates. Use the following workaround to generate self-signed certificates. All commands are executed while connected to the master node.

    1. Copy the certificate generation script from the container to the master node:

       sudo docker cp jupyterhub:/tmp/gen_self_signed_cert.sh ./

    2. Use a text editor to change line 23 to change public hostname to local hostname as shown below:

       local hostname=$(curl -s $EC2_METADATA_SERVICE_URI/local-hostname)

    3. Run the script to generate self-signed certificates:

       sudo bash ./gen_self_signed_cert.sh

    4. Move the certificate files that the script generates to the /etc/jupyter/conf/ directory:

       sudo mv /tmp/server.crt /tmp/server.key /etc/jupyter/conf/

    You can tail the jupyter.log file to verify that JupyterHub restarted and is returning a 200 response code. For example:

    tail -f /var/log/jupyter/jupyter.log

    This should return a response similar to the following:

    # [I 2018-06-14 18:56:51.356 JupyterHub app:1581] JupyterHub is now running at https://:9443/
    # 19:01:51.359 - info: [ConfigProxy] 200 GET /api/routes

Initial release date: March 29, 2018

Changes, Enhancements, and Resolved Issues

• Updated the Amazon Linux kernel of the default Amazon Linux AMI for Amazon EMR to address potential vulnerabilities.

Release 5.12.1 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 need changes from community versions for Amazon EMR. These components have a version label in the form CommunityVersion-amzn-EmrVersion. For example, if a big-data community component named myapp-component of version 2.2 has been modified three times for inclusion in different Amazon EMR release versions, its release version is listed as 2.2-amzn-3.
