> KeeperException.NoNodeException and NotEmptyException should be ignored when deleting a zLock or its parent in ZooKeeperHiveLockManager unlockPrimitive. The exceptions can happen: 
> 1) ZooKeeperHiveLockManager retries deleting a zLock after a failure but it has been deleted. 
> 2) a race condition where another process adds a zLock just before it is about to be deleted.
> Otherwise, unlock may unnecessarily be retried for numRetriesForUnLock times.
