Jonathan Eagles updated YARN-2277:
----------------------------------

    Description: 
As the Application Timeline Server is not provided with built-in UI, it may 
make sense to enable JSONP or CORS Rest API capabilities to allow for remote UI 
to access the data directly via javascript without cross side server browser 
blocks coming into play.

Example client may be like
http://api.jquery.com/jQuery.getJSON/ 

This can alleviate the need to create a local proxy cache.
