> After the region server rolls back a timed out attempt of  region split, the region became
unavailable. 
> Symptoms:
> The RS displayed the region open in the web UI.
> The meta table still pointed to the RS
> Requests for the regions received a NotServingRegionException. 
> hbck reported 0 inconsistencies. 
> Moving the region failed. 
> Restarting the region server fixes the problem.
> We have see multiple occurrences which requires operation intervention.
