>
> The reason of this is that AM gets the proxy URI from config
> yarn.web-proxy.address, and if it does not exist, it will get the URI from
> yarn.resourcemanager.webapp.address.
> But in federation, we don't know which RM will be the home cluster of an
> application, so I do this fix:
> 1. Add this config in the yarn-site.xml on client.
> <property>
> <name>yarn.web-proxy.address</name>
> <value>rm1:9088,rm2:9088</value>
> </property>
> 2. Change the way to get the config from Configuration#get to
> Configuration#getStrings in WebAppUtils#getProxyHostsAndPortsForAmFilter.
> So that I can access the AM page now.
> This config need to be added in the client side, so it will affect
> application only.
