> Discovered via HBASE-7250; related to HBASE-5877.
> Test is writing from multiple threads.
> Server A has region R; client knows that.
> R gets moved from A to server B.
> B gets killed.
> R gets moved by master to server C.
> ~15 seconds later, client tries to write to it (on A?).
> Multiple client threads report from RegionMoved exception processing logic "R
> moved from C to B", even though such transition never happened (neither in
> nor before the sequence described below). Not quite sure how the client
> learned of the transition to C, I assume it's from meta from some other
> thread...
> Then, put fails (it may fail due to accumulated errors that are not logged,
> which I am investigating... but the bogus cache update is there
> nonwithstanding).
> I have a patch but not sure if it works, test still fails locally for yet
> unknown reason.
