Release date: 10/08/2020

This release applies for both HDInsight 3.6 and HDInsight 4.0. HDInsight release is made available to all regions over several days. The release date here indicates the first region release date. If you don't see below changes, wait for the release being live in your region in several days.

New features

HDInsight private clusters with no public IP and Private link (Preview)

HDInsight now supports creating clusters with no public IP and private link access to the clusters in preview. Customers can use the new advanced networking settings to create a fully isolated cluster with no public IP and use their own private endpoints to access the cluster.

Moving to Azure virtual machine scale sets

HDInsight now uses Azure virtual machines to provision the cluster. Starting from this release, the service will gradually migrate to Azure virtual machine scale sets. The entire process may take months. After your regions and subscriptions are migrated, newly created HDInsight clusters will run on virtual machine scale sets without customer actions. No breaking change is expected.

Deprecation

Deprecation of HDInsight 3.6 ML Services cluster

HDInsight 3.6 ML Services cluster type will be end of support by Dec 31 2020. Customers won't create new 3.6 ML Services clusters after that. Existing clusters will run as is without the support from Microsoft. Check the support expiration for HDInsight versions and cluster types here.

Upcoming changes

The following changes will happen in upcoming releases.

Ability to select different Zookeeper virtual machine sizes for Spark, Hadoop, and ML Services

HDInsight today doesn't support customizing Zookeeper node size for Spark, Hadoop, and ML Services cluster types. It defaults to A2_v2/A2 virtual machine sizes, which are provided free of charge. In the upcoming release, you can select a Zookeeper virtual machine size that is most appropriate for your scenario. Zookeeper nodes with virtual machine size other than A2_v2/A2 will be charged. A2_v2 and A2 virtual machines are still provided free of charge.

Component version change

No component version change for this release. You can find the current component versions for HDInsight 4.0 and HDInsight 3.6 in this doc.
