> In assigning a region, assignment manager forces the region state offline if
> it is not. This could cause double assignment, for example, if the region is
> already assigned and in the Open state, you should not just change it's state
> to Offline, and assign it again.
> I think this could be the root cause for all double assignments IF the region
> state is reliable.
> After this loophole is closed, TestHBaseFsck should come up a different way
> to create some assignment inconsistencies, for example, calling region server
> to open a region directly.
