Monthly updates for HDInsight: November 2019
Azure HDInsight—Simplify NSG rules management using service tags
Azure HDInsight now supports the use of service tags to simplify inbound network security group (NSG) rule management. Azure service tags group multiple IP addresses under a single user friendly tag. Administrators need to only create rules by referring to the tags while Microsoft takes the responsibility of keeping the IP addresses up to date. Administrators maintaining Azure HDInsight clusters can now benefit from this manageability improvement.
Azure HDInsight—Autoscale is now generally available
Autoscale for Azure HDInsight is now generally available across all regions for Apache Spark and Hadoop workloads. This feature makes it possible to operate your big data analytics workloads in a more cost-efficient and productive way, so you can drive higher use of your HDInsight clusters and pay only for what you need.
HDInsight HBase Accelerated Writes is now generally available
Target availability: Q4 2019
The accelerated writes feature in the HDInsight HBase cluster attaches a Premium SSD managed disk to every region server (worker node). Write ahead logs are configured to be written to Hadoop Distributed File System (HDFS) mounted on premium managed disks instead of standard Azure page blobs. Premium managed disks are SSD-based and offer excellent I/O performance with fault tolerance. Using premium managed disks for WALs allows us to separate write ahead log storage from Apache HBase data storage.
Azure HDInsight now enables you to customize Azure SQL Database for Ambari
A new Azure HDInsight capability enables you to customize and upgrade your Azure SQL Database for Apache Ambari during cluster creation.
Azure HDInsight—Restrict outbound network traffic by using Firewall
Target availability: Q4 2019
The integration of Azure HDInsight and Azure Firewall, in order to restrict outbound traffic from the cluster to unauthorized destinations, is now generally available.
