             Summary: Revisit default retry config for connection with RM 
                 Key: YARN-4060
                 URL: https://issues.apache.org/jira/browse/YARN-4060
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Jian He
            Assignee: Jian He

15 minutes timeout for AM/NM connection with RM in non-ha scenario turns out to 
be  short in production environment.  The suggestion is to increase that to 30 
min. Also, the retry-interval is set to 30 seconds which appears too long. We 
may reduce that to 10 seconds ?
