• You can now create an AWSCredentialsProvider for use with EMRFS using a URI as a parameter. For more information, see Create an AWSCredentialsProvider for EMRFS.

• EMRFS now allows users to configure a custom DynamoDB endpoint for their Consistent View metadata using the fs.s3.consistent.dynamodb.endpoint property in emrfs-site.xml.

• Added a script in /usr/bin called spark-example, which wraps /usr/lib/spark/spark/bin/run-example so you can run examples directly. For instance, to run the SparkPi example that comes with the Spark distribution, you can run spark-example SparkPi 100 from the command line or using command-runner.jar as a step in the API.

Known Issues Resolved from Previous Releases

• Fixed an issue where Oozie had the spark-assembly.jar was not in the correct location when Spark was also installed, which resulted in failure to launch Spark applications with Oozie.

• Fixed an issue with Spark Log4j-based logging in YARN containers.

Release 4.7.0 Release Notes

Important

Amazon EMR 4.7.0 is deprecated. Use Amazon EMR 4.7.1 or later instead.

Release date: June 2, 2016

Features

• Added Apache Phoenix 4.7.0

• Added Apache Tez 0.8.3

• Upgraded to HBase 1.2.1

• Upgraded to Mahout 0.12.0

• Upgraded to Presto 0.147

• Upgraded the AWS SDK for Java to 1.10.75

• The final flag was removed from the mapreduce.cluster.local.dir property in mapred-site.xml to allow users to run Pig in local mode.

• Amazon Redshift JDBC Drivers Available on Cluster

  Amazon Redshift JDBC drivers are now included at /usr/share/aws/redshift/jdbc. /usr/share/aws/redshift/jdbc/RedshiftJDBC41.jar is the JDBC 4.1-compatible Amazon Redshift driver and /usr/share/aws/redshift/jdbc/RedshiftJDBC4.jar is the JDBC 4.0-compatible Amazon Redshift driver. For more information, see Configure a JDBC Connection in the Amazon Redshift Cluster Management Guide.

• Java 8

  Except for Presto, OpenJDK 1.7 is the default JDK used for all applications. However, both OpenJDK 1.7 and 1.8 are installed. For information about how to set JAVA_HOME for applications, see Configuring Applications to Use Java 8.

Known Issues Resolved from Previous Releases

• Fixed a kernel issue that significantly affected performance on Throughput Optimized HDD (st1) EBS volumes for Amazon EMR in emr-4.6.0.

• Fixed an issue where a cluster would fail if any HDFS encryption zone were specified without choosing Hadoop as an application.

• Changed the default HDFS write policy from RoundRobin to AvailableSpaceVolumeChoosingPolicy. Some volumes were not properly utilized with the RoundRobin configuration, which resulted in failed core nodes and an unreliable HDFS.

• Fixed an issue with the EMRFS CLI, which would cause an exception when creating the default DynamoDB metadata table for consistent views.

• Fixed a deadlock issue in EMRFS that potentially occurred during multipart rename and copy operations.

• Fixed an issue with EMRFS that caused the CopyPart size default to be 5 MB. The default is now properly set at 128 MB.

• Fixed an issue with the Zeppelin upstart configuration that potentially prevented you from stopping the service.

• Fixed an issue with Spark and Zeppelin, which prevented you from using the s3a:// URI scheme because /usr/lib/hadoop/hadoop-aws.jar was not properly loaded in their respective classpath.

• Backported HUE-2484.

• Backported a commit from Hue 3.9.0 (no JIRA exists) to fix an issue with the HBase browser sample.

• Backported HIVE-9073.

The following release notes include information for the Amazon EMR 4.6.0 release.

• Added HBase 1.2.0

• Added Zookeeper-Sandbox 3.4.8

• Upgraded to Presto-Sandbox 0.143

• Amazon EMR releases are now based on Amazon Linux 2016.03.0. For more information, see https://aws.amazon.com/amazon-linux-ami/2016.03-release-notes/.

• Issue Affecting Throughput Optimized HDD (st1) EBS Volume Types

  An issue in the Linux kernel versions 4.2 and above significantly affects performance on Throughput Optimized HDD (st1) EBS volumes for EMR. This release (emr-4.6.0) uses kernel version 4.4.5 and hence is impacted. Therefore, we recommend not using emr-4.6.0 if you want to use st1 EBS volumes. You can use emr-4.5.0 or prior Amazon EMR releases with st1 without impact. In addition, we provide the fix with future releases.

• Python Defaults

  Python 3.4 is now installed by default, but Python 2.7 remains the system default. You may configure Python 3.4 as the system default using either a bootstrap action; you can use the configuration API to set PYSPARK_PYTHON export to /usr/bin/python3.4 in the spark-env classification to affect the Python version used by PySpark.

• Java 8

  Except for Presto, OpenJDK 1.7 is the default JDK used for all applications. However, both OpenJDK 1.7 and 1.8 are installed. For information about how to set JAVA_HOME for applications, see Configuring Applications to Use Java 8.

Known Issues Resolved from Previous Releases

• Fixed an issue where application provisioning would sometimes randomly fail due to a generated password.

• Previously, mysqld was installed on all nodes. Now, it is only installed on the master instance and only if the chosen application includes mysql-server as a component. Currently, the following applications include the mysql-server component: HCatalog, Hive, Hue, Presto-Sandbox, and Sqoop-Sandbox.

• Changed yarn.scheduler.maximum-allocation-vcores to 80 from the default of 32, which fixes an issue introduced in emr-4.4.0 that mainly occurs with Spark while using the maximizeResourceAllocation option in a cluster whose core instance type is one of a few large instance types that have the YARN vcores set higher than 32; namely c4.8xlarge, cc2.8xlarge, hs1.8xlarge, i2.8xlarge, m2.4xlarge, r3.8xlarge, d2.8xlarge, or m4.10xlarge were affected by this issue.

• s3-dist-cp now uses EMRFS for all Amazon S3 nominations and no longer stages to a temporary HDFS directory.

• Fixed an issue with exception handling for client-side encryption multipart uploads.

• Added an option to allow users to change the Amazon S3 storage class. By default this setting is STANDARD. The emrfs-site configuration classification setting is fs.s3.storageClass and the possible values are STANDARD, STANDARD_IA, and REDUCED_REDUNDANCY. For more information about storage classes, see Storage Classes in the Amazon Simple Storage Service Developer Guide.

Release 4.6.0 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 release versions, its release version is listed as 2.2-amzn-2.
