> In the resource manager log, yarn would log the command for launching AM,
> this is very useful. But there's no such log in the NN log for launching
> containers. It would be difficult to diagnose when containers fails to launch
> due to some issue in the commands. Although user can look at the commands in
> the container launch script file, this is an internal things of yarn, usually
> user don't know that. In user's perspective, they only know what commands
> they specify when building yarn application.
