> [Federation] Improve DefaultRequestInterceptor#init Code
> --------------------------------------------------------
>
> Key: YARN-11515
> URL: https://issues.apache.org/jira/browse/YARN-11515
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: federation, router
> Affects Versions: 3.4.0
> Reporter: Shilun Fan
> Assignee: Shilun Fan
> Priority: Minor
> Labels: pull-request-available
>
> If we do not enable Federation mode, the YARN Router can also act as a proxy
> for the YARN ResourceManager. In this case, we can achieve this functionality
> by configuring the DefaultRequestInterceptor. While reading the code, I
> found that the Init code could be improved.
