Jeff Zhang updated YARN-3755:
-----------------------------
Description:
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.
