Updated

  • MSI based authentication support available for Azure blob storage.

    • Azure HDInsight now supports OAuth-based authentication for accessing Azure Blob storage by leveraging Azure Active Directory (AAD) and managed identities (MSI). With this enhancement, HDInsight uses user-assigned managed identities to access Azure blob storage. For more information, see Managed identities for Azure resources.
  • HDInsight service is transitioning to use standard load balancers for all its cluster configurations because of deprecation announcement of Azure basic load balancer.

    • This change will be rolled out in a phased manner for different regions.

    Note

    Standard LB changes in HDInsight are available in all public regions except US East, US East2, US West, US West2, US South Central, US Gov Regions, and China regions.

    This change will be available in these pending regions effective January 9, 2025.

    Important

    When using your own Virtual Network (custom VNet) during cluster creation, please be advised that the cluster creation will not succeed once this change is enabled. We recommend referring to the migration guide to recreate the cluster. For any assistance, contact support.

Coming soon

  • 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.
  • Retirement Notifications for HDInsight 4.0 and HDInsight 5.0.
