Description

I setup a yarn federation cluster, I can't connect the running app web, but the completed and accepted app's web works.

So I think need two step: 

(a) YARN-11153: make proxy server support federation. (YARN-11153)

(b) YARN-11154: make router support proxy server.

Though it is a not difficult problem, but not easy to describe the problem. So I submit a document YARN-10775-design-doc.001.pdf to explain this.

 

If standalone proxyserver is enable, after step (a), the problem is solved.

If standalone proxyserver is disable, after step (a) and (b), we use router as web proxy server, so we hide the cluster info for client, I think it is reasonable.
