title: shell/action.xml file not found after oozie completes the w/f, and fails
body: <p>I am running spark jobs on oozie, but the workflow fails some times with the exception File does not exist: /user/hadoop/oozie-oozi/0096734-161228053611212-oozie-oozi-W/workflowName--shell/action.xml </p>
  
  <p>I am not able to find the root cause, when I rerun the failed step it succeeds. 
  We recently added new nodes to the cluster, Can there be any config issue ?
  Have anyone faced similar issue ? </p>
