zhengchenyu commented on YARN-10786:
------------------------------------
I don't think it's a good way to solve this problem.
I think yarn client shouldn't know resourcemanager's address in federation
mode. we may adjust the back yarn sub-cluster, so resourcemanager's address may
be not constant.
In the other way, If we have more than one subcluster, this way may be not good.
In fact, we solve this problem by some solution like song jiacheng. But I think
it's not a good solution .I create YARN-10775 before, hope to discuss this
problem.

> Project: Hadoop YARN
> Issue Type: Bug
> Components: federation
> Affects Versions: 3.2.1

> Priority: Major
> Labels: federation
> Fix For: 3.2.1

>
>
> 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 needs to be added in the client side, so it will affect
> application only.
> Before fixing， click the AM link in RM or Router：

> And after the fix, we can access the AM page as normal...
