You can now use Apache Hadoop 2.8.3, Apache HBase 1.4.0, Apache Flink 1.4.0, Presto 0.188, and Presto integration with EMRFS on Amazon EMR release 5.12.0. Additionally, you can now use upgraded versions of Hue (4.1.0), Apache MXNet (1.0.0), and Apache Phoenix (4.13.0). Hadoop 2.8.3 is the first version of Hadoop 2.8.x supported in Amazon EMR and contains many improvements and bug fixes to YARN and HDFS. HBase 1.4.0 adds new features including support for binary row keys in the REST client and an optional new HFile block structure for faster random read performance. Flink 1.4.0 features several new features including a support for aggregation on streaming tables and enhancements to Flink SQL. Presto now supports using the EMR File System (EMRFS) to performantly access data in Amazon S3. This enables you to use EMRFS features like consistent view, S3 server-side and client-side encryption, and EMRFS authorization with Presto.
You can create an Amazon EMR cluster with the release 5.12.0 by choosing the release label "emr-5.12.0" from the AWS Management Console, AWS CLI, or SDK. You can select Flink, Hadoop, HBase, Hue, MXNet, Phoenix, and Presto when you launch your EMR cluster. Presto is now configured to use EMRFS by default on release 5.12.0 and later. Please visit the Amazon EMR documentation for more information about release 5.12.0, Hadoop 2.8.3, Flink 1.4.0, Presto 0.188, Hue 4.1.0, HBase 1.4.0, MXNet 1.0.0, Phoenix 4.13.0, and EMRFS.
