> GCMulitpleMergedRegionsProcedure is not idempotent

> Key: HBASE-24316
> URL: https://issues.apache.org/jira/browse/HBASE-24316
> Project: HBase
> Issue Type: Bug
> Components: proc-v2
> Affects Versions: 3.0.0-alpha-1, 2.3.0, 2.4.0
> Reporter: Huaxiang Sun
> Assignee: Huaxiang Sun
> Priority: Major
> Fix For: 3.0.0-alpha-1, 2.3.0, 2.4.0
>
>
> Currently deleteMergeQualifiers() is not idempotent. If two
> GCMulitpleMergedRegionsProcedures are run for the same merged child region,
> the second run will delete the row for the merge region from meta table and
> leave a hole. It needs to make sure it only deletes columns with merge
> qualifiers.
