Suma Shivaprasad commented on YARN-7935:
----------------------------------------

This is no longer needed since the container's hostname, IP and additional 
information could be obtained via YARN-8659 by Spark or other AMs which need 
this information.

> Expose container's hostname to applications running within the docker 
> container

> Some applications have a need to bind to the container's hostname (like 
> Spark) which is different from the NodeManager's hostname(NM_HOST which is 
> available as an env during container launch) when launched through Docker 
> runtime. The container's hostname can be exposed to applications via an env 
> CONTAINER_HOSTNAME. Another potential candidate is the container's IP but 
> this can be addressed in a separate jira.
