[jira] [Created] (YARN-8925) Updating distributed node attributes only when necessary

Tao Yang created YARN-8925:
------------------------------

             Summary: Updating distributed node attributes only when necessary
                 Key: YARN-8925
                 URL: https://issues.apache.org/jira/browse/YARN-8925
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: resourcemanager
    Affects Versions: 3.2.1
            Reporter: Tao Yang
            Assignee: Tao Yang


Currently if distributed node attributes exist, even though there is no change, updating for distributed node attributes will happen in every heartbeat between NM and RM. Updating process will hold NodeAttributesManagerImpl#writeLock and may have some influence in a large cluster. We have found nodes UI of a large cluster is opened slowly and most time it's waiting for the lock in NodeAttributesManagerImpl. I think this updating should be called only when necessary to enhance the performance of related process.
