Jonathan Gray commented on HBASE-3203:
--------------------------------------

looks fine to me.  kind of unfortunate we have new 'stopping' state, but guess 
we need it because can't just have 'stopped' earlier?  makes sense i suppose.  
anything else we want to reject if closing?

good fix on that completely wrong comment :)

+1 to commit if you've done some testing w/ it

> We can get an order to open a region while shutting down and it'll hold up 
> regionserver shutdown

> Starting and stopping clusters I see that an open directive can come in while 
> we are shutting down all the user space regions on a particular regionserver. 
>  Regionservers will only shut themselves down after all user space regions 
> have closed.  We queue up all the closes at a particular time.  If an open 
> comes in while we are in the closing condition, then the regionserver won't 
> go down.  The region open needs to be blocked.
