> Key: HBASE-21222
> URL: https://issues.apache.org/jira/browse/HBASE-21222
> Project: HBase
> Issue Type: Bug
> Components: amv2
> Reporter: stack
> Assignee: stack
> Priority: Major
>
> Ran into this one where a Region had been on a server but after a bunch of crashing and meddling in Master Proc WALs, any attempt at unassign has the procedure fail (see below) and then report the region as STUCK.
> I broke the lock w/ new hbck2 tooling and then tried to offline again but same thing happened. Bug. Fix.
