Subject [jira] [Created] (HBASE-11290) Unlock RegionStates
Date Tue, 03 Jun 2014 05:57:01 GMT
Francis Liu created HBASE-11290:

             Summary: Unlock RegionStates
                 Key: HBASE-11290
                 URL: https://issues.apache.org/jira/browse/HBASE-11290
             Project: HBase
          Issue Type: Sub-task
            Reporter: Francis Liu
            Assignee: Francis Liu

Even though RegionStates is a highly accessed data structure in HMaster. Most of it's methods
are synchronized. Which limits concurrency. Even simply making some of the getters non-synchronized
by using concurrent data structures has helped with region assignments. We can go as simple
as this approach or create locks per region or a bucket lock per region bucket.
