> 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?
