> Typically, YARN Router serves multiple YARN sub-clusters in what we refer to 
> as YARN Federation. In this scenario, there are two or more YARN 
> sub-clusters, and Router, based on queue configuration weights, forwards 
> client requests to a specific sub-cluster.
> However, YARN Router also offers the capability to directly forward client 
> requests to a particular local cluster. This functionality has already been 
> implemented, and you can refer to components such as 
> DefaultRequestInterceptorREST, DefaultClientRequestInterceptor, and 
> DefaultRMAdminRequestInterceptor.
> In this JIRA ticket, we aim to enhance the functionality of YARN Router Web 
> to display information about a specific local cluster.
