Craig Welch commented on YARN-1994:

Trying to understand the scenario here - is it the case that you have a host 
with multiple interfaces where some resolve on the host to a different name 
from the actual host name, but for some clients on other networks it resolves 
to the same name as the box (so, to a different name than the box sees for it's 
own interface)?  Do I understand properly that the basic issue is that there is 
an interface on the box with a name different from what you want to use based 
on the address, but you do somehow want to bind to that name and will be able 
to use it from a client somewhere?  For that to happen, the client would need 
to resolve the name differently and/or have a different yarn config with a 
different address in it, is that what is happening?

> YARN and MapReduce daemons currently do not support specifying a wildcard 
> address for the server endpoints. This prevents the endpoints from being 
> accessible from all interfaces on a multihomed machine.
> Note that if we do specify INADDR_ANY for any of the options, it will break 
> clients as they will attempt to connect to We need a solution that 
> allows specifying a hostname or IP-address for clients while requesting 
> wildcard bind for the servers.
