> 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
