Description

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.
