> If a client gets confused (possibly by a hole in .META., see HBASE-4333), it 
> may send a request to the wrong region.  Paths through put, delete, 
> incrementColumnValue, and checkAndMutate all call checkRow either directly or 
> indirectly (through getLock).  But get apparently does not.  This can result 
> in returning an incorrect empty result instead of a WrongRegionException.
