Subject [jira] Created: (HBASE-3337) Restore HBCK fix of unassignment and dupe assignment for new master
Date Mon, 13 Dec 2010 18:32:11 GMT
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.
