Jonathan Hung updated YARN-7974:
--------------------------------
    Description: 
Normally an application's tracking url is set on AM registration. We have a use 
case for updating the tracking url after registration (e.g. the UI is hosted on 
one of the containers).

Approach is for AM to update tracking url on heartbeat to RM, and add related 
API in AMRMClient.

Normally an application's tracking url is set on AM registration. We have a use 
case for updating the tracking url after registration (e.g. the UI is hosted on 
one of the containers).

Currently we added a {{updateTrackingUrl}} API to ApplicationClientProtocol.

We'll post the patch soon, assuming there are no issues with this.
