--------------------------------------
I'm happy to make a 0.94 patch. But just to be doubly sure, we only want this
in 0.94, right?
> Balancer compete with disable table will lead to cluster inconsistent

> Balancer will collect the regionplans to move(unassign and then assign).
> before unassign, disable table appears,
> after close the region in rs, master will delete the znode, romove region
> from RIT,
> and then clean the region from the online regions.
> During romoving region from RIT and cleaning out the region from the online
> regions.
> balancer begins to unassign, it will get a NotServingRegionException and if
> the table is disabling, it will deal with the state in master and delete the
> znode . However the table is disabled now, so the RIT and znode will remain.
> TimeoutMonitor draws a blank on it.
> It will hold back enabling the table or balancer unless restart
