Review Comment:
Thank you very much for your help reviewing the code! Our default processing
method is to allow partial results to be returned, but if the user sets it to
`false`, we will have to get all the results correctly before returning them.
If a subCluster throws an exception, we will return the exception directly.

> URL: https://issues.apache.org/jira/browse/YARN-11358
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: federation, router
> Affects Versions: 3.4.0
> Reporter: fanshilun
> Assignee: fanshilun
> Priority: Major
> Labels: pull-request-available
>
> When we use Federation, we will have multiple sub-clusters, and some
> interfaces need to call all clusters to get results,
> such as getNodes, getNodeToLabels, etc.
> But if the sub-cluster is unavailable when we call the interface, should the
> interface return the result?
> The current code is to return the result.If the result is returned, the
> result information is inaccurate;
> if the result is not returned, it is not user-friendly
> We'd better add a parameter control, the user chooses whether to report an
> error or return the result.
