             Summary: Increase the default value of 
yarn.timeline-service.app-collector.linger-period.ms
                 Key: YARN-8156
                 URL: https://issues.apache.org/jira/browse/YARN-8156
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Rohith Sharma K S


The default value of *yarn.timeline-service.app-collector.linger-period.ms* is 
1 sec which is very low. In production cluster, we observe that most of the 
entity information is not published because of 1sec linger period. 

I would suggest to increase the default value to either 10sec or 30sec or 60 
sec. As far as I have seen, 10sec should be sufficient since node heartbeat 
period is 3 sec by default, all NM gets request to stop the application.
