> I setup a yarn federation cluster, I can't connect the running app web, but the completed app's web works.
> By some debug info, I found the reason. Because AmIpFilter.PROXY_HOSTS is set by configuration (do it in AmFilterInitializer.getProxyHostsAndPortsForAmFilter). In client configuration, there are no configuation about 'rm web port', so the url can't not be redirect. 
> I think client should not know rm's web port, especially in yarn federation mode.
> Note:
> Here is my specially configuration for client. I use ha for select router randomly.
> || config || value ||
> | yarn.resourcemanager.ha.enabled   | true |
> | yarn.resourcemanager.ha.rm-ids | r1 |
> |yarn.resourcemanager.address.r1 | router_host:8050 |
> |yarn.resourcemanager.scheduler.address.r1 | localhost:8049 |
