> When JobClient (runs as yarn user) uses RM_DELEGATION_TOKEN (owner:oozie) to submit the
job, client uses /mapreducestaging/yarn as staging directory whereas MRAppMaster uses /mapreducestaging/oozie.
This leads to below failure

> Job init failed : org.apache.hadoop.yarn.exceptions.YarnRuntimeException: java.io.FileNotFoundException:
