Issues fixed

  • Managed identity-based authentication for WASB encounters issues when network ACL is enabled on storage.
  • Managed identity-based authentication for SQL databases encounters issues when availability zones are used.
  • Multiple security fixes.

Updates

  • Active PIN requests for creating HDInsight clusters with predetermined image versions will be revoked/cancelled on 26 May 2025. Beyond this date, customers will only be able to create clusters using the updated (compliant) images of each HDInsight version. This measure is intended to improve cluster security and prevent potential issues with clusters and gateway nodes.

Reminder

  • HDInsight service transitioned to use standard load balancers for all its cluster configurations due to deprecation announcement of Azure basic load balancer.

    Important

    By default, creation of any new HDInsight cluster happens with Standard Load Balancers. We recommend referring to the migration guide to recreate the cluster. For any assistance, contact support.

  • Basic and Standard A-series VMs Retirement.

    • On August 31, 2024, we'll retire Basic and Standard A-series VMs. Before that date, you need to migrate your workloads to Av2-series VMs, which provide more memory per vCPU and faster storage on solid-state drives (SSDs).
    • To avoid service disruptions, migrate your workloads from Basic and Standard A-series VMs to Av2-series VMs before August 31, 2024.

If you have any more questions, contact Azure Support.
