             Summary: [Atsv2] Remove timeline.service.address dependency for starting Timeline Reader in secure mode 
                 Key: YARN-7662
                 URL: https://issues.apache.org/jira/browse/YARN-7662
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Rohith Sharma K S


While starting Timeline Reader in secure mode, login happens using timeline.service.address even though timeline.service.bindhost is configured with 0.0.0.0. This causes exact principal name that matches address name to be present in keytabs. 

It is always better to login using getLocalHost that gives machine hostname which is configured in /etc/hosts unlike NodeManager does in serviceStart.
