> Components: master, Region Assignment
> Affects Versions: 2.0.0
> Reporter: Andrey Stepachev

>
> Got situation where region can be opened while table is disabling by
> DisableTableHandler. Here is relevant log for such situation. There is no
> clues who issued OPEN to region.
> Log file attached.
> UPD: A bit more details. It seems that even in case of new state put into
> meta, it still possible to get previous state.
> That leads to one more round of assignment invoked in
> AssignmentManager#onRegionClosed.
> UPD: Table become ENABLED, thats leads to regions instructed to assign
> immediately on onRegionClosed. BulkDisabler will not know about that and will
> wait indefinitely, because it will not issue unassign for newly opened
> regions.
