4.6.0 release notes
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/python3.4in thespark-envclassification 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_HOMEfor 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,
mysqldwas installed on all nodes. Now, it is only installed on the master instance and only if the chosen application includesmysql-serveras a component. Currently, the following applications include themysql-servercomponent: HCatalog, Hive, Hue, Presto-Sandbox, and Sqoop-Sandbox. -
Changed
yarn.scheduler.maximum-allocation-vcoresto 80 from the default of 32, which fixes an issue introduced in emr-4.4.0 that mainly occurs with Spark while using themaximizeResourceAllocationoption 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. Theemrfs-siteconfiguration classification setting isfs.s3.storageClassand the possible values areSTANDARD,STANDARD_IA, andREDUCED_REDUNDANCY. For more information about storage classes, see Storage Classes in the Amazon Simple Storage Service User Guide.
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-EmrVersionEmrVersionmyapp-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.
