Sidharta Seethana commented on YARN-5298:
-----------------------------------------

Thanks, [~vvasudev] and [~templedf] !

[~vvasudev] , about the container specific directories : The docker container 
runtime itself makes no assumptions about the location of the container 
specific directories/non container-specific directories. It does not know of or 
assume a parent/sub-dir structure and explicitly mounts all required 
directories. I hope that answers your question.

> Currently, we don't mount the usercache and the NM filecache directories into 
> the Docker container. This can lead to issues with containers that rely on 
> public and application scope resources.
