Wangda Tan commented on YARN-5323:
----------------------------------
Thanks [~curino],
Some questions / comments:
1) Who will consume AMRMProxyFederationPolicy and RouterFederationPolicy? I'm
not be able to figure it out from the patch, I guess AMRMProxyService will use
them, is it correct?
2) It looks like FederationPolicy is more like a
FederationConfigurator/Creator, is it better to remove the FederationPolicy
interface? We can either make FederationPolicyConfigurator extends
FederationPolicyWriter or let implementation decide which to implement (such as
{{SimpleFederationPolicyConfiguratorImpl implements FederationPolicyWriter,
FederationPolicyConfigurator}}).
3) Is it better to rename FederationPolicyContext to
FederationPolicyInitializationContext?
4) The name "router" is a little hard to be understood, now it only determines
application's home sub cluster while submitting the app, do you plan to add
more functionalities to the module? Do you think is it better to rename it to
be "AMRMProxyHomeClusterPolicy", (and similarly we may rename
AMRMProxyFederationPolicy to AMRMProxyResourceRequestPolicy).
