public class ClusterUserInfo
extends Object

The YARN UI doesn't have centralized login mechanism. While accessing UI2 from kerberized shell, user who is placed the request to YARN need to be displayed in UI. Given requests from UI2 is routed via Proxy, only RM can provide the user who has placed the request. This DAO object help to provide the requested user and also RM logged in user. the response sent by RM is authenticated user instead of proxy user. It is always good to display authenticated user in browser which eliminates lot of confusion to end use.
