The YARN ResourceManager UI runs on the cluster headnode. It's accessed through the Ambari web UI. Concepts and Flow.

After YarnClient is started, the client can then set up application context, prepare the very first container of the application that contains the ApplicationMaster (AM), and then submit the application.
