> yarn logs does not output attemptid, nodename, or container-id.  Missing these makes
it very difficult to look through the logs for failed containers and tie them back to actual
tasks and task attempts.
> Also the output currently includes several binary characters.  This is OK for being machine
readable, but difficult for being human readable, or even for using standard tool like grep.
> The help message can also be more useful to users
