> Very similar to HBASE-1928, but for the general case (not just ROOT/META):
> If a region is in transition on a RS when the RS crashes, the master does not
> remove it from regionsInTransition when processing the RS shutdown. This is
> fairly easy to trigger by bringing up a RS and kill -9ing it just as it
> starts to get regions assigned. Those regions will get permanently lost since
> they're stuck in regionsInTransition and thus don't get assigned by the
> metascanner.
