> 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.
