stack commented on HBASE-4287:
------------------------------
Patch looks good. The new state I'm not mad about, not without our first
having done a review in toto of all possible states to figure what new states
we're missing, but I'm grand with this going in.
> If region opening fails, try to transition region back to "offline" in ZK

> In the case that region-opening fails, we currently just close the region
> again, but don't do anything to the node in ZK. Instead, we should attempt to
> transition it from the OPENING state back to an OFFLINE state, or perhaps a
> new FAILED_OPEN state. Otherwise, we have to wait for the full timeoutMonitor
> period to elapse, which can be quite a long time.
