  • Artikel

Applies to: SQL Server 2019 (15.x)

Important

The Microsoft SQL Server 2019 Big Data Clusters add-on will be retired. Support for SQL Server 2019 Big Data Clusters will end on February 28, 2025. All existing users of SQL Server 2019 with Software Assurance will be fully supported on the platform and the software will continue to be maintained through SQL Server cumulative updates until that time. For more information, see the announcement blog post and Big data options on the Microsoft SQL Server platform.

One of the key scenarios for big data clusters is the ability to submit Spark jobs for SQL Server. The Spark job submission feature allows you to submit a local Jar or Py files with references to SQL Server 2019 big data cluster. It also enables you to execute a Jar or Py files, which are already located in the HDFS file system.
