[jira] Created: (HBASE-3188) Review locking around AssignmentManager.regionPlans

Review locking around AssignmentManager.regionPlans
---------------------------------------------------

                 Key: HBASE-3188
                 URL: https://issues.apache.org/jira/browse/HBASE-3188
             Project: HBase
          Issue Type: Improvement
          Components: master
    Affects Versions: 0.90.0
            Reporter: Jonathan Gray
            Priority: Minor


AssignmentManager.regionPlans is currently a ConcurrentSkipListMap so does not require synchronization.  But sometimes we do multiple operations and we synchronize on it.  But other times we don't synchronize on it at all.

Let's review and make sure we're doing the right thing.

Also see if we still need this AssignmentManager.updateTimers().  Don't we disable load balancer / expiration during startup or no?
