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 Amazon 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 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.

4.7.0 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.
