Jonathan Gray commented on HBASE-3138:
--------------------------------------
The issue is we don't have an HRI for the region-in-transition because we can't
get to META. Without the HRI, we can't properly setup the state in RIT map.
We could serialize the HRI into the RIT node and use it there (right now we
have byte [] regionName in there).
> When new master joins running cluster but meta is yanked from it as
> processing RIT, gets unexpected state
