Basically, just remove the corresponding action classes that you do not want Oozie to support. 4. Save and restart Oozie After that, if you try to run a SSH action through Oozie, it will fail. And sample error from Hue looks like below: Please keep in mind that if you do make this change, remember to check the version of Oozie that you will upgrade to in the future, to make sure that the new supported classes are added to this list, otherwise other jobs will fail. For example, currently Oozie can only support running Spark1 action, Spark2 is not supported. However, in latest CDH version 6.x, Spark2 is now supported and the list will need to be updated.
