Sunil G commented on YARN-5877:
-------------------------------
[~bibinchundatt] and [~varun_saxena]
Ideally there will be difference with NM context and system ENV only in Docker
scenario.
I am not against new configuration. But how can user know which config to use.
In case of normal launch, there are no difference with these 2 configurations.
Only in docker, there are difference. So i think are we going a case which is
only for docker? if so, configuration also need to be docker specific
Thoughts?
