Subru Krishnan commented on YARN-5410:
--------------------------------------
Thanks [~leftnoteasy] for your feedback.
bq. I think I understand the purpose of Router. However, since it implements
ClientRMService, it behaves as gateway of RM. I'm not sure if any logics could
be shared with resource-manager module.
bq. If you're confident with router will be independent from RM, I'm fine with
creating this sub module
The Router will only be a *proxy* to the RM and we will be following an
interceptor pattern (ala servlet filters) exactly like we did with the
{{AMRMProxy}} for the AM - RM protocol in YARN-2884. So the Router will depend
on the {{ApplicationClientProtocol}} and {{FederationStateStore}}
(yarn-server-common module) which are independent of RM.
Hope this makes sense?
