------------------------------------
Summary: Hbck needs to call Master.offlineRegion() to clean
in-memory state after issuing a RS.closeRegion()
Key: HBASE-21037
URL: https://issues.apache.org/jira/browse/HBASE-21037
Project: HBase
Issue Type: Bug
Components: hbck
Affects Versions: 1.2.6
Reporter: huaxiang sun
Assignee: huaxiang sun
In certain cases, hbck issues a RS.closeRegion() to close a region from RS. It
does not clean up in-memory state from master for the offlined region and
balancer will bring back the closed region, causing region inconsistency.
certain codes needs to be reexamined to see a Master.offlineRegion() is needed.
