> Question: Looking at this patch again, if we throw a RegionAlreadyInTransitionException, won't we just assign the region elsewhere though RegionAlreadyInTransitionException in at least one case here is saying that the region is already open on this regionserver?

> Indeed looking at the code it's going to be handled the same way other exceptions are. Need to add special cases for assign and unassign.
