> Ran into this while trying to find out why region_mover.rb was not catching an exception after a region was split. Digging further I found that the problem is happening in the handling of the region state in the Master since we don't remove the old state after the split is successful:

> {code}
> I don't think the problem is happening in the master branch but at least I've been able to confirm this is happening on branch-1 and branch-1.2 at least.
