> After the region server rolls back a timed out attempt of region split, the
> region becomes unavailable.
> Symptoms:
> The RS displays the region open in the web UI.
> The meta table still points to the RS

> hbck reports 0 inconsistencies.
> Moving the region fails.
> Restarting the region server fixes the problem.
> We have see multiple occurrences which require operation intervention.
