Naganarasimha G R commented on YARN-4119:

Only problem i can see with the above approach is that, by default it binds to 
{{NM_WEBAPP_ADDRESS}} and not on all IPs which we thought of having as default 
behavior !

>  Expose the NM bind address as an env, so that AM can make use of it for 
> exposing tracking URL

> As described in MAPREDUCE-5938, In many security scanning tools its not 
> advisable to bind on all network addresses and would be good to bind only on 
> the desired address. As AM's can run on any of the nodes it would be better 
> for NM to share its bind address as part of Environment variables to the 
> container.
