Wellington Chevreuil updated HBASE-30353:
-----------------------------------------
Component/s: Region Assignment
> Split parent regions can be re-opened
> -------------------------------------
>
> Key: HBASE-30353
> URL: https://issues.apache.org/jira/browse/HBASE-30353
> Project: HBase
> Issue Type: Bug
> Components: Region Assignment
> Affects Versions: 3.0.0
> Reporter: Tanya Stickles
> Assignee: Tanya Stickles
> Priority: Major
> Labels: pull-request-available
>
> After an HMaster failover, a region split can be undone and reopened by a
> RegionServer. If compaction runs on the zombie parents, it archives the store
> files the daughter regions reference. The daughters are then unreachable.
> Reads on the daughter regions return a FileNotFoundException.
>
> Expected behavior: The master should reject any attempt to assign a split
> parent region.
