  1. Enhanced Autoscale for HDInsight

    Azure HDInsight has made notable improvements stability and latency on Autoscale, The essential changes include improved feedback loop for scaling decisions, significant improvement on latency for scaling and support for recommissioning the decommissioned nodes, Learn more about the enhancements, how to custom configure and migrate your cluster to enhanced autoscale. The enhanced Autoscale capability is available effective 17 May, 2023 across all supported regions.

  2. Azure HDInsight ESP for Apache Kafka 2.4.1 is now Generally Available.

    Azure HDInsight ESP for Apache Kafka 2.4.1 has been in public preview since April 2022. After notable improvements in CVE fixes and stability, Azure HDInsight ESP Kafka 2.4.1 now becomes generally available and ready for production workloads, learn the detail about the how to configure and migrate.

  3. Quota Management for HDInsight

    HDInsight currently allocates quota to customer subscriptions at a regional level. The cores allocated to customers are generic and not classified at a VM family level (For example, Dv2, Ev3, Eav4, etc.).

    HDInsight introduced an improved view, which provides a detail and classification of quotas for family-level VMs, this feature allows customers to view current and remaining quotas for a region at the VM family level. With the enhanced view, customers have richer visibility, for planning quotas, and a better user experience. This feature is currently available on HDInsight 4.x and 5.x for East US EUAP region. Other regions to follow later.

  • Poland Central

Coming soon

  • The max length of cluster name will be changed to 45 from 59 characters, to improve the security posture of clusters.
  • Cluster permissions for secure storage
    • Customers can specify (during cluster creation) whether a secure channel should be used for HDInsight cluster nodes to contact the storage account.
  • In-line quota update.
    • Request quotas increase directly from the My Quota page, which will be a direct API call, which is faster. If the API call fails, then customers need to create a new support request for quota increase.
  • HDInsight Cluster Creation with Custom VNets.
    • To improve the overall security posture of the HDInsight clusters, HDInsight clusters using custom VNETs will need to ensure that the user needs to have permission for Microsoft Network/virtualNetworks/subnets/join/action to perform create operations. Customers would need to plan accordingly as this would be a mandatory check to avoid cluster creation failures.
  • Basic and Standard A-series VMs Retirement.
    • On 31 August 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 31 August 2024.
  • Non-ESP ABFS clusters [Cluster Permissions for World Readable]
    • Plan to introduce a change in non-ESP ABFS clusters, which restricts non-Hadoop group users from executing Hadoop commands for storage operations. This change to improve cluster security posture. Customers need to plan for the updates.
