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.
