Restore HBCK fix of unassignment and dupe assignment for new master
-------------------------------------------------------------------
Key: HBASE-3337
URL: https://issues.apache.org/jira/browse/HBASE-3337
Project: HBase
Issue Type: Bug
Components: master, util
Reporter: Jonathan Gray
Assignee: Jonathan Gray
Priority: Critical
Fix For: 0.90.0, 0.92.0
HBCK fixing of region unassignment and duplicate assignment was broken with the
move to the new master.
We've seen it happen doing testing of 0.90 RCs like that over in HBASE-3332.
Rather than the old "clear everything out approach" which relied on the
BaseScanner, in the new master we should just manipulate unassigned ZK nodes
and let the master handle the transition.
