             Summary: Some improvements required in Dump scheduler logs
                 Key: YARN-4451
                 URL: https://issues.apache.org/jira/browse/YARN-4451
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Naganarasimha G R
            Assignee: Naganarasimha G R


Though dumping scheduler logs is very useful option there are few nits in using it
* for naive or first time user its hard to understand what does {{"Time"}} stand for past or future, IMO it would be slightly better to set the name in the ui as {{"Time Period"}}
* success message should give where the logs will be found and the file name
* Need to append the time stamp and the period to the file name, so that its not over ridden
* From code it seems like it always returns {{"Capacity scheduler logs are being created"}} even though the fair scheduler is set
* Would having cli option in {{"yarn rmadmin"}}  will also be helpful ?
