> 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.
