Botong Huang commented on YARN-7900:
------------------------------------
Hi [~asuresh], yes I understand. I don't think I am breaking this requirement
though. After the flattening, everything in {{List<SchedulingRequest>
schedulingRequests}} will still be put into the {{allocate}} call each time. I
did this change because it simplify the code a bit, and the code pattern
becomes more consistent with other channels, i.e. release, updates, blacklists.
Please let me know what you think.

> Inside stateful FederationInterceptor (YARN-7899), we need a component
> similar to AMRMClient that remembers all pending (outstands) requests we've
> sent to YarnRM, auto re-register and do full pending resend when YarnRM fails
> over and throws ApplicationMasterNotRegisteredException back. This JIRA adds
> this component as AMRMClientRelayer.
