OpenedRegionHandler racing with itself in ServerShutDownhandler flow leading to HMaster abort
---------------------------------------------------------------------------------------------

                 Key: HBASE-4539
                 URL: https://issues.apache.org/jira/browse/HBASE-4539
             Project: HBase
          Issue Type: Bug
            Reporter: ramkrishna.s.vasudevan
            Assignee: ramkrishna.s.vasudevan


Steps to reproduce
==================
-> Region R1 is being opened in RS1.  
->After processing the znode to OPENED RS1 goes down.
->Now before the OpenedRegionHandler executor deletes the znode if ServerShutDownHandler
tries to assign the region to RS2, RS2 transits the node to OPENED and this OpenedRegionHandler
executor deletes the znode.  
->Now if the first OpenedRegionHandler tries deleting the znode it throws NoNode Exception
and causes the HMaster to abort.
