Li Lu commented on YARN-3148:

Hi [~varun_saxena], thanks for working on this! For the current patch, since we're supporting
more fields, maybe it's helpful to add some tests? 

BTW, I checked and the current patch would not apply. I'm canceling this patch for now. Thanks.

> currently the WebAppProxyServlet filters the request headers as defined by  passThroughHeaders.
Tez UI is building a webapp which using rest api to fetch data from the am via the rm tracking
> for this purpose it would be nice to have additional headers allowed especially the ones
related to CORS. A few of them that would help are

> * Access-Control-Request-Method
> * Access-Control-Request-Headers
