----------------------------------------------------------
Thanks a lot for the detailed design documentation, the documentation is very
clear.
1.I personally think that resource manage should not assume the role of
proxyserver,
I feel that this operation should be implemented on the router, the router
should know the rm list, but the rm should not know the router list, each rm
should be able to run independently.
2.I don't think there is a problem with letting the client know the location of
rms, just like viewfs, the client will know the location of all namenodes. The
advantage of letting the client know the cluster list is that if the router
fails, it can traverse the SubCluster list to ensure that the job can be
submitted and the cluster as a whole will not be unavailable.
3.Thank you very much for your design doc, but can you provide the
documentation for the version supported by router.

> Key: YARN-10775
> URL: https://issues.apache.org/jira/browse/YARN-10775
> Project: Hadoop YARN
> Issue Type: Bug
> Reporter: zhengchenyu
> Assignee: zhengchenyu
> Priority: Major
> Attachments: YARN-10775-design-doc.001.pdf
>
>
> 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) make proxy server support federation.
> (b) 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.
