Jonathan Eagles commented on YARN-2277:
---------------------------------------

Exactly. Cross-origin (perhaps 3rd party) UI could be more easily written.

> Add Cross-Origin support to the ATS REST API

> 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.
