region assignment can become stale and master doesnt fix it
-----------------------------------------------------------
Key: HBASE-1461
URL: https://issues.apache.org/jira/browse/HBASE-1461
Project: Hadoop HBase
Issue Type: Bug
Affects Versions: 0.20.0
Reporter: ryan rawson
Fix For: 0.20.0
I have been playing with ZK recovery and other crash scenarios. There is a
very rare but potential bug where a region can be assigned to be open on an
existing regionserver, but the regionserver itself doesn't have the region open.
The HMaster should also check the opposite of what it does - make sure that
regions assigned to server X are actually _open_ on that server.
