Wangda Tan commented on YARN-6550:
----------------------------------

Thanks [~suma.shivaprasad], 

+1 to skip printing stack trace for non zero exit code.

In general patch LGTM, only one naming suggestions in generated script for readability:
- {{export STDOUT}} to {{PRELAUNCH_OUT}}, and {{STDERR}} to {{PRELAUNCH_ERR}}

> launch_container.sh which generated by NM will do a bunch of things (like create link,
etc.) while launch a process. No logs captured until {{exec}} is called. We need capture all
failures of launch_container.sh for easier troubleshooting.
