> 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.
