             Summary: Optimize locks in NodeStateMap
                 Key: HDDS-11647
                 URL: https://issues.apache.org/jira/browse/HDDS-11647
             Project: Apache Ozone
          Issue Type: Improvement
          Components: SCM
            Reporter: weiming


In NodeStateMap, we use a global ReentrantReadWriteLock. We should probably use 
a finer-grained lock to control concurrent operations, so we try to use 
Striped<ReadWriteLock> to optimize the lock implementation.
