Bo Cui commented on HBASE-22614:
--------------------------------
[~wchevreuil] if the cluster has a lot of overlapping regions,hbase shell is
not available.
> Master should provide the ability to delete a specified region
> --------------------------------------------------------------

> Key: HBASE-22614
> URL: https://issues.apache.org/jira/browse/HBASE-22614
> Project: HBase
> Issue Type: Improvement
> Components: hbck
> Affects Versions: 1.3.1, 2.1.0
> Reporter: Bo Cui
> Priority: Major
>
> If there is a overlap in hbase, it can not be fixed completely with hbck,
> because there is old regioninfo in master regionStates.
> Key reproducible steps:
> 1.Constructing a overlap scenario（region1 and region2 have the same
> startKey,region1 is opend on the regionserver1,region2 is opend on the
> regionserver2）
> 2.use hbck repair
> 3.regionserver1 or regionserver2 aborted
> 4.region1 or region2 is reopened
>
> Master should provide the ability to remove a specified region, and hbck uses
> the ability.
> {code:java}
> public deleteSpecifiedRegion(regionName){
> if(MetaTableAccessor.getRegionResult(regionName)==null){
> RegionStates.removeRegion(regionName)
> }
> }
> {code}
