Steve Loughran commented on YARN-4085:
--------------------------------------
Make it an env var, maybe one per limit (if unset for that var == not limited;
allows for new resource limiting to be added later (YARN_CONTAINER_LIMIT_IO ...
)
> Generate file with container resource limits in the container work dir

> Priority: Minor

> Currently, a container doesn't know what resource limits are being imposed on
> it. It would be helpful if the NM generated a simple file in the container
> work dir with the resource limits specified.
