--------------------------------------
Summary: Split parent regions can be re-opened
Key: HBASE-30353
URL: https://issues.apache.org/jira/browse/HBASE-30353
Project: HBase
Issue Type: Bug
Reporter: Tanya Stickles
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.
