> Key: YARN-11509
> URL: https://issues.apache.org/jira/browse/YARN-11509
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: amrmproxy
> Affects Versions: 3.4.0
> Reporter: Shilun Fan
> Assignee: Shilun Fan
> Priority: Minor
> Labels: pull-request-available
> Fix For: 3.4.0
>
>
> There is a "todo" in the
> FederationInterceptor#registerAndAllocateWithNewSubClusters method. According
> to the "todo" description, the request needs to be retried to other
> subclusters, but changing the parameter requests in
> registerAndAllocateWithNewSubClusters is not a good operation. It is better
> to add retry logic here.
> We don't need to worry about losing requests because when the request cannot
> be satisfied, the AM of the task will continue to apply, and these requests
> will be properly transferred to other clusters for execution.
