> [AMRMProxy] FederationInterceptor upgrade: home sub-cluster heartbeat async
> ---------------------------------------------------------------------------
>
> Key: YARN-8696
> URL: https://issues.apache.org/jira/browse/YARN-8696
> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Botong Huang
> Assignee: Botong Huang
> Priority: Major
> Attachments: YARN-8696-branch-2.v6.patch, YARN-8696.v1.patch,
> YARN-8696.v2.patch, YARN-8696.v3.patch, YARN-8696.v4.patch,
> YARN-8696.v5.patch, YARN-8696.v6.patch
>
>
> Today in _FederationInterceptor_, the heartbeat to home sub-cluster is
> synchronous. After the heartbeat is sent out to home sub-cluster, it waits
> for the home response to come back before merging and returning the (merged)
> heartbeat result to back AM. If home sub-cluster is suffering from connection
> issues, or down during an YarnRM master-slave switch, all heartbeat threads
> in _FederationInterceptor_ will be blocked waiting for home response. As a
> result, the successful UAM heartbeats from secondary sub-clusters will not be
> returned to AM at all. Additionally, because of the fact that we kept the
> same heartbeat responseId between AM and home RM, lots of tricky handling are
> needed regarding the responseId resync when it comes to
> _FederationInterceptor_ (part of AMRMProxy, NM) work preserving restart
> (YARN-6127, YARN-1336), home RM master-slave switch etc.
> In this patch, we change the heartbeat to home sub-cluster to asynchronous,
> same as the way we handle UAM heartbeats in secondaries. So that any
> sub-cluster down or connection issues won't impact AM getting responses from
> other sub-clusters. The responseId is also managed separately for home
> sub-cluster and AM, and they increment independently. The resync logic
> becomes much cleaner.
