Brandon DeVries created NIFI-1547:
-------------------------------------

             Summary: DistributedMapCacheServer: Ambiguous error on misconfiguration
                 Key: NIFI-1547
                 URL: https://issues.apache.org/jira/browse/NIFI-1547
             Project: Apache NiFi
          Issue Type: Bug
            Reporter: Brandon DeVries
            Priority: Minor


If a DistributedMapCacheServer's "Persistence Directory" is set to the same location as another DistributedMapCacheServer (or another controller service with a  "Persistence Directory") only one will enable successfully.  The other(s) will get an OverlappingFileLockException.  Consider catching this exception \[1\] and providing additional information (e.g. check the lock location /  "Persistence Directory").
