Description

There is corner case where leaking happens.
when workflow KillCommand is issued, WfEndXCommand is invoked in the end finally block, and WfEndXCommand.deleteWFDir() kills action Dir (e.g., /user/satish/oozie_satish/123450-15000000000000-oozie_satish-W)
but, when this happens right before launcher mapper uploading actionData to HDFS, previously deleted actionDir is created again. the actionDir will not be cleaned up after. This leak can fill up namespace quota of user over a period of time.

The solution is to delete clean up action dir in ActionKillXCommand.
