Removing Hive on Spark Configurations

Your scripts, or queries, include the Hive on Spark configuration, which is no longer supported, and you must know how to recognize and remove these configurations.

In CDP, there is no Hive-Spark dependency. The Spark site and libs are not in the classpath. This execution engine has been replaced by Apache Tez.

Before Upgrade to CDP

CDH supported Hive on Spark and the following configuration to enable Hive on Spark: set hive.execution.engine=spark

After Upgrade to CDP

CDP does not support Hive on Spark. Scripts that enable Hive on Spark do not work.

Action Required

Remove set hive.execution.engine=spark from your scripts.
