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 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 Use 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-siteandcapacity-schedulerconfiguration 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, andgcc48are no longer installed by default. These can be installed if desired usingyum. -
The aws-sdk ruby gem is no longer installed by default. It can be installed using
gem install aws-sdk, if desired. Specific components can also be installed. For example,gem install aws-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.
-
CloudWatch ContainerPending Metric and Automatic Scaling—(Fixed in 5.20.0)Amazon EMR may emit a negative value for
ContainerPending. IfContainerPendingis used in an automatic scaling rule, automatic scaling does not behave as expected. Avoid usingContainerPendingwith automatic scaling. In Amazon EMR version 5.19.0, 5.20.0, and 5.21.0, YARN node labels are stored in an HDFS directory. In some situations, this leads to core node startup delays and then causes cluster time-out and launch failure. Beginning with Amazon EMR 5.22.0, this issue is resolved. YARN node labels are stored on the local disk of each cluster node, avoiding dependencies on HDFS.
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 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.
