Botong Huang commented on YARN-5531:
------------------------------------
Thanks [~kasha] for the review! For 2, sure I will add more logs. For 1, to me
this class is more like a utility rather than a service, which hides the fact
that this is an UAM in the remote Yarn cluster, and present an aync version of
{ApplicationMasterProtocol} RM interface to user (the actual AM). We can modify
it into a service as well if needed.
[~subru]: along this line of thought, maybe we should call this class
UnmanagedApplicationMasterProxy? Thanks!

> One of the main tenets the YARN Federation is to *transparently* scale
> applications across multiple clusters. This is achieved by running UAMs on
> behalf of the application on other clusters. This JIRA tracks the addition of
> a UnmanagedAM pool manager for federating application across clusters which
> will be used the FederationInterceptor (YARN-3666) which is part of the
> AMRMProxy pipeline introduced in YARN-2884.
