> Key: HBASE-30352
> URL: https://issues.apache.org/jira/browse/HBASE-30352
> Project: HBase
> Issue Type: Bug
> Components: master
> Affects Versions: 3.0.0, 2.5.16, 2.6.7
> Reporter: Nirdosh Kumar Yadav
> Assignee: Nirdosh Kumar Yadav
> Priority: Minor
>
> {color:#172b4d}When MergeTableRegionsProcedure fails at the
> MERGE_TABLE_REGIONS_CHECK_CLOSED_REGIONS state — e.g. because
> AssignmentManagerUtil.checkClosedRegion() throws "Recovered.edits are found
> in Region: … abort split/merge to prevent data loss" — the procedure
> framework unwinds through rollbackState(). The
> MERGE_TABLE_REGIONS_CHECK_CLOSED_REGIONS case is a bare break;, so the
> parents that were CLOSED during the prior forward step
> MERGE_TABLE_REGIONS_CLOSE_REGIONS are never re-opened. Both parent regions
> remain OFFLINE and the RIT can persist indefinitely until an operator
> intervenes. So we will check the max seq ID of recovered edits and compare
> with max Seq ID of region and Ignore if recovered edits are stale. {color}
