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?
