--------------------------------

             Summary: Local directory health checks should not only find 
problems at the local dir level but also at the usercache and filecache level 
                 Key: YARN-6700
                 URL: https://issues.apache.org/jira/browse/YARN-6700
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: nodemanager
            Reporter: Grant Sohn
            Priority: Minor


Chmod 400 the usercache directory.  The node manager doesn't notice that the 
usercache is no longer usable.  Since the usercache and filecache are part of 
the local dir, we should extend the checks on these too.
