Jimmy Xiang commented on HBASE-6858:
------------------------------------
It should throw a BADVERSION exception, as expected, in this case. We can't
violate the semantics.
Very likely, the client(s) is trying to doing something it thinks only it's
doing. It could be done many times, which is ok.
If it should be done only once, then it is a problem.
