> On our cluster which based 2.2.0, we found one problem: there are some opened
> regions which had wrong regionserver in meta. The regionserver is not exist.
> We used hbck2 to fix them by the following steps.
> # disable table
> # bypass the stucked close region procedure (as the target regionserver is
> not exist) and disable table procedure.
> # setRegionState to CLOSED.
> # setTableState to DISABLED.
> # enable table
> We found this problem by scan the hbase:meta. I thought we should add this
> feature to hbck2. The we can use hbck2 to find this problem. Thanks.
