> Handle AM register requests asynchronously in FederationInterceptor
> -------------------------------------------------------------------
>
> Key: YARN-7652
> URL: https://issues.apache.org/jira/browse/YARN-7652
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: amrmproxy, federation
> Affects Versions: 2.9.0, 3.0.0
> Reporter: Subru Krishnan
> Assignee: Botong Huang
> Priority: Major
> Fix For: 2.10.0, 3.3.0
>
> Attachments: YARN-7652.v1.patch, YARN-7652.v2.patch
>
>
> We (cc [~goiri]/[~botong]) observed that the {{FederationInterceptor}} in
> {{AMRMProxy}} (and consequently the AM) is blocked if the _StateStore_ has
> outdated info about a _SubCluster_. This is because we handle AM register
> requests synchronously. This jira proposes to move to async similar to how we
> operate with allocate invocations.
