Arun Suresh commented on YARN-7900:
-----------------------------------
[~subru], This code touches some of the changes we made for YARN-6592, which is
not there in branch-2.. so I don't think it will be a trivial cherry-pick.
[~botong], feel free to re-open and attach a branch-2 patch
> [AMRMProxy] AMRMClientRelayer for stateful FederationInterceptor

> 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.
