Elliott Clark commented on HBASE-14311:
---------------------------------------

However the only time that I see more than one region being transitioned is when a region splits. So I'm not 100% sure.

> We just had a master that was stuck even though only reportRegionInTransitions that contain meta are handled by priority handlers.
> From what I can tell reading the code I think that's because lots of regions can be in transition on a regionserver. However the master only handles them in order that the rs sends them. Not in a priority order.
