Spark 3 support in Oozie

This section describes how to re-enable the Spark actions, provides guidance on migrating your workflows from Spark actions to Spark 3 actions, highlights the differences between the two, and outlines the enhancements made to Spark actions to simplify the migration process.

Due to the discontinuation and deprecation of Spark 2, Oozie's Spark actions are deprecated, which are based on Spark 2. Consequently, Oozie's Spark actions are disabled by default, and if you attempt to execute a Spark action, an error appears. Oozie supports the new Spark 3 based Spark 3 actions.
