> 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.
