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 
    

5.14.0 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.

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.

Release 5.12.0 Application Versions

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

Release 5.12.0 Release Notes

The following release notes include information for the Amazon EMR release version 5.12.0. Changes are relative to 5.11.1.

Upgrades

• AWS SDK for Java 1.11.238 ⇒ 1.11.267. For more information, see the AWS SDK for Java Change Log on GitHub.

• Hadoop 2.7.3 ⇒ 2.8.3. For more information, see Apache Hadoop Releases.

• Flink 1.3.2 ⇒ 1.4.0. For more information, see the Apache Flink 1.4.0 Release Announcement.

• HBase 1.3.1 ⇒ 1.4.0. For more information, see the HBase Release Announcement.

• Hue 4.0.1 ⇒ 4.1.0. For more information, see the Release Notes.

• MxNet 0.12.0 ⇒ 1.0.0. For more information, see the MXNet Change Log on GitHub.

• Presto 0.187 ⇒ 0.188. For more information, see the Release Notes.

Changes, Enhancements, and Resolved Issues

• Hadoop

  • The yarn.resourcemanager.decommissioning.timeout property has changed to yarn.resourcemanager.nodemanager-graceful-decommission-timeout-secs. You can use this property to customize cluster scale-down. For more information, see Cluster Scale-Down in the Amazon EMR Management Guide.

  • The Hadoop CLI added the -d option to the cp (copy) command, which specifies direct copy. You can use this to avoid creating an intermediary .COPYING file, which makes copying data between Amazon S3 faster. For more information, see HADOOP-12384.

• Pig

  • Added the pig-env configuration classification, which simplifies the configuration of Pig environment properties. For more information, see Configuring Applications.

• Presto

  • Added the presto-connector-redshift configuration classification, which you can use to configure values in the Presto redshift.properties configuration file. For more information, see Redshift Connector in Presto documentation, and Configuring Applications.

  • Presto support for EMRFS has been added and is the default configuration. Earlier Amazon EMR release versions used PrestoS3FileSystem, which was the only option. For more information, see EMRFS and PrestoS3FileSystem Configuration.

    Note

    A configuration issue can cause Presto errors when querying underlying data in Amazon S3 with Amazon EMR release version 5.12.0. This is because Presto fails to pick up configuration classification values from emrfs-site.xml. As a workaround, create an emrfs subdirectory under usr/lib/presto/plugins/hive-hadoop2/, create a symlink in usr/lib/presto/plugins/hive-hadoop2/emrfs to the existing /usr/share/aws/emr/emrfs/conf/emrfs-site.xml file, and then restart the presto-server process (sudo presto-server stop followed by sudo presto-server start).

• Spark

  • Backported SPARK-22036: BigDecimal multiplication sometimes returns null.

Known Issues

• MXNet does not include OpenCV libraries.

• SparkR is not available for clusters created using a custom AMI because R is not installed by default on cluster nodes.

Changes, Enhancements, and Resolved Issues

• Updated the Amazon Linux kernel of the default Amazon Linux AMI for Amazon EMR to address vulnerabilities associated with speculative execution (CVE-2017-5715, CVE-2017-5753, and CVE-2017-5754). For more information, see https://aws.amazon.com/security/security-bulletins/AWS-2018-013/.

Release 5.11.1 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.

Release 5.11.0 Application Versions

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

Release 5.11.0 Release Notes

The following release notes include information for the Amazon EMR release version 5.11.0. Changes are relative to 5.10.0.

Upgrades

• Hive 2.3.2

• Spark 2.2.1

• SDK for Java 1.11.238

New Features

• Spark

  • Added spark.decommissioning.timeout.threshold setting, which improves Spark decommissioning behavior when using Spot Instances. For more information, see Configuring Node Decommissioning Behavior.

  • Added the aws-sagemaker-spark-sdk component to Spark, which installs Amazon SageMaker Spark and associated dependencies for Spark integration with Amazon SageMaker. You can use Amazon SageMaker Spark to construct Spark machine learning (ML) pipelines using Amazon SageMaker stages. For more information, see the SageMaker Spark Readme on GitHub and Using Apache Spark with Amazon SageMaker in the Amazon SageMaker Developer Guide.

Known Issues

• MXNet does not include OpenCV libraries.

• Hive 2.3.2 sets hive.compute.stats.using.query=true by default. This causes queries to get data from existing statistics rather than directly from data, which could be confusing. For example, if you have a table with hive.compute.stats.using.query=true and upload new files to the table LOCATION, running a SELECT COUNT(*) query on the table returns the count from the statistics, rather than picking up the added rows.

  As a workaround, use the ANALYZE TABLE command to gather new statistics, or set hive.compute.stats.using.query=false. For more information, see Statistics in Hive in the Apache Hive documentation.

• Added support for Apache MXNet.

Changes, Enhancements, and Resolved Issues

• Presto

  • Added support for using the AWS Glue Data Catalog as the default Hive metastore. For more information, see Using Presto with the AWS Glue Data Catalog.

  • Added support for geospatial functions.

  • Added spill to disk support for joins.

  • Added support for the Redshift connector.

• Spark

  • Backported SPARK-20640, which makes the rpc timeout and the retries for shuffle registration values configurable using spark.shuffle.registration.timeout and spark.shuffle.registration.maxAttempts properties.

  • Backported SPARK-21549, which corrects an error that occurs when writing custom OutputFormat to non-HDFS locations.

• Backported Hadoop-13270

• The Numpy, Scipy, and Matplotlib libraries have been removed from the base Amazon EMR AMI. If these libraries are required for your application, they are available in the application repository, so you can use a bootstrap action to install them on all nodes using yum install.

• The Amazon EMR base AMI no longer has application RPM packages included, so the RPM packages are no longer present on cluster nodes. Custom AMIs and the Amazon EMR base AMI now reference the RPM package repository in Amazon S3.

• Because of the introduction of per-second billing in Amazon EC2, the default Scale down behavior is now Terminate at task completion rather than Terminate at instance hour. For more information, see Configure Cluster Scale-Down.

Known Issues

• MXNet does not include OpenCV libraries.

• Hive 2.3.1 sets hive.compute.stats.using.query=true by default. This causes queries to get data from existing statistics rather than directly from data, which could be confusing. For example, if you have a table with hive.compute.stats.using.query=true and upload new files to the table LOCATION, running a SELECT COUNT(*) query on the table returns the count from the statistics, rather than picking up the added rows.

  As a workaround, use the ANALYZE TABLE command to gather new statistics, or set hive.compute.stats.using.query=false. For more information, see Statistics in Hive in the Apache Hive documentation.

Release 5.10.0 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.

Release 5.9.0 Release Notes

The following release notes include information for the Amazon EMR version 5.9.0 release. Changes are relative to the Amazon EMR 5.8.0 release.

Release date: October 5, 2017

Latest feature update: October 12, 2017

Upgrades

• AWS SDK for Java version 1.11.183

• Flink 1.3.2

• Hue 4.0.1

• Pig 0.17.0

• Presto 0.184

New Features

• Added Livy support (version 0.4.0-incubating). For more information, see Apache Livy.

• Added support for Hue Notebook for Spark.

• Added support for i3-series Amazon EC2 instances (October 12, 2017).

Changes, Enhancements, and Resolved Issues

• Spark

  • Added a new set of features that help ensure Spark handles node termination because of a manual resize or an automatic scaling policy request more gracefully. For more information, see Configuring Node Decommissioning Behavior.

  • SSL is used instead of 3DES for in-transit encryption for the block transfer service, which enhances performance when using Amazon EC2 instance types with AES-NI.

  • Backported SPARK-21494.

• Zeppelin

  • Backported ZEPPELIN-2377.

• HBase

  • Added patch HBASE-18533, which allows additional values for HBase BucketCache configuration using the hbase-site configuration classification.

• Hue

  • Added AWS Glue Data Catalog support for the Hive query editor in Hue.

  • By default, superusers in Hue can access all files that Amazon EMR IAM roles are allowed to access. Newly created users do not automatically have permissions to access the Amazon S3 filebrowser and must have the filebrowser.s3_access permissions enabled for their group.

• Resolved an issue that caused underlying JSON data created using AWS Glue Data Catalog to be inaccessible.

Known Issues

• Cluster launch fails when all applications are installed and the default Amazon EBS root volume size is not changed. As a workaround, use the aws emr create-cluster command from the AWS CLI and specify a larger --ebs-root-volume-size parameter.

• Hive 2.3.0 sets hive.compute.stats.using.query=true by default. This causes queries to get data from existing statistics rather than directly from data, which could be confusing. For example, if you have a table with hive.compute.stats.using.query=true and upload new files to the table LOCATION, running a SELECT COUNT(*) query on the table returns the count from the statistics, rather than picking up the added rows.

  As a workaround, use the ANALYZE TABLE command to gather new statistics, or set hive.compute.stats.using.query=false. For more information, see Statistics in Hive in the Apache Hive documentation.

Release 5.8.2 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 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.

Release 5.8.0 Application Versions

The following applications are supported in this release: Flink, Ganglia, Hadoop, HBase, HCatalog, Hive, Hue, Mahout, Oozie, Phoenix, Pig, Presto, Spark, Sqoop, 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)

Release 5.8.0 Release Notes

The following release notes include information for the Amazon EMR version 5.8.0 release. Changes are relative to the Amazon EMR 5.7.0 release.

Initial release date: August 10, 2017

Latest feature update: September 25, 2017

Upgrades

• AWS SDK 1.11.160

• Flink 1.3.1

• Hive 2.3.0. For more information, see Release Notes on the Apache Hive site.

• Spark 2.2.0. For more information, see Release Notes on the Apache Spark site.

New Features

• Added support for viewing application history (September 25, 2017). For more information, see Viewing Application History in the Amazon EMR Management Guide.

Changes, Enhancements, and Resolved Issues

• Integration with AWS Glue Data Catalog

  • Added ability for Hive and Spark SQL to use AWS Glue Data Catalog as the Hive metadata store. For more information, see Using the AWS Glue Data Catalog as the Metastore for Hive and Using the AWS Glue Data Catalog as the Metastore for Spark SQL.

• Added Application history to cluster details, which allows you to view historical data for YARN applications and additional details for Spark applications. For more information, see View Application History in the Amazon EMR Management Guide.

• Oozie

  • Backported OOZIE-2748.

• Hue

  • Backported HUE-5859

• HBase

  • Added patch to expose the HBase master server start time through Java Management Extensions (JMX) using getMasterInitializedTime.

  • Added patch that improves cluster start time.

Known Issues

• Cluster launch fails when all applications are installed and the default Amazon EBS root volume size is not changed. As a workaround, use the aws emr create-cluster command from the AWS CLI and specify a larger --ebs-root-volume-size parameter.

• Hive 2.3.0 sets hive.compute.stats.using.query=true by default. This causes queries to get data from existing statistics rather than directly from data, which could be confusing. For example, if you have a table with hive.compute.stats.using.query=true and upload new files to the table LOCATION, running a SELECT COUNT(*) query on the table returns the count from the statistics, rather than picking up the added rows.

  As a workaround, use the ANALYZE TABLE command to gather new statistics, or set hive.compute.stats.using.query=false. For more information, see Statistics in Hive in the Apache Hive documentation.

• Spark—When using Spark, there is a file handler leak issue with the apppusher daemon, which can appear for a long-running Spark job after several hours or days. To fix the issue, connect to the master node and type sudo /etc/init.d/apppusher stop. This stops that apppusher daemon, which Amazon EMR will restart automatically.

• Application history

  • Historical data for dead Spark executors is not available.

  • Application history is not available for clusters that use a security configuration to enable in-flight encryption.

Release 5.5.2 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 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.
