             Summary: Log the IO Exception when deleting worker pid dir
                 Key: STORM-1667
                 URL: https://issues.apache.org/jira/browse/STORM-1667
             Project: Apache Storm
          Issue Type: Bug
            Reporter: Zhuo Liu
            Assignee: Zhuo Liu


There is a race condition since shutdown-worker is called by both 
sync-processes and synchronize-supervisor. One pid directory might have been 
already deleted when rmr-as-user tries to delete it. 
Therefore, we should not let the FileNotFoundException get thrown and crash the 
supervisor.
