-----------------------------------

             Summary: ATS TimelineACLsManager checkAccess is slow
                 Key: YARN-8589
                 URL: https://issues.apache.org/jira/browse/YARN-8589
             Project: Hadoop YARN
          Issue Type: Bug
          Components: timelineserver
    Affects Versions: 2.7.3
            Reporter: Prabhu Joseph


ATS rest api is very slow when there are more than 1lakh entries if yarn.acl.enable is set to true as TimelineACLsManager has to check access for every entries. We can;t disable yarn.acl.enable as all the YARN ACLs uses the same config. We can have a separate config to provide read access to the ATS Entries.
