[!INCLUDEsqlserver]

This article describes the [!INCLUDEssDE] features that are no longer available in [!INCLUDEssnoversion].

Discontinued features in [!INCLUDEsssql22]

  • The following Machine Learning Services packages are no longer included with installation of [!INCLUDE sssql22-md]. Instead, you can install any custom packages as desired. For more information, see What's new in SQL Server Machine Learning Services?

    Language Package
    Python microsoftml
    R olapR
    R sqlrutils
    R MicrosoftML (R)

  • SQL Server Big Data Clusters will be retired. See information in [[!INCLUDEbig-data-cluster] overview](../big-data-cluster/big-data-cluster-overview.md).

  • SQL Server PolyBase scale-out groups will be retired. Scale out group functionality is removed from the product in [!INCLUDE sssql22-md]. PolyBase data virtualization continues to be fully supported as a scale-up feature in SQL Server.

  • Support for Hadoop (HDFS) external data sources will be retired for SQL Server PolyBase.

  • See Changes to PolyBase support in SQL Server.

  • Starting in [!INCLUDE sssql22-md], Hadoop external data sources are no longer supported. It is required to manually recreate external data sources previously created with TYPE = HADOOP, and any external table that uses this external data source. Users will also need to configure their external data sources to use new connectors when connecting to Azure Storage.
