Issues fixed

  • Authentication issue for SQL databases when managed identity is used.

Updates

  • Active PIN requests for creating HDInsight clusters with predetermined image versions stand revoked/cancelled as of 26 May 2025. Customers can only 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 has 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.

If you have any more questions, contact Azure Support.
