> 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.
