> 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 ?
