> YARN web proxy not forwards hadoop-jwt token.
> So if we
> - have a YARN application (lets say spark)
> - and we check the RM UI2 via KNOX proxy
> - and we click the +ApplicationMaster+ link on the application page of the
> spark app
> The browser will be forwarded to the SparkAM ui
> for example: /gateway/cdp-proxy/yarnuiv2/proxy/application_1771935206205_0001/
> KNOX wont receive the hadoop-jwt cookie, so will ask user to login.
> Instead of this if we can pass the jwt cookie for the KNOX so the user can
> see the AM UI after login state, and wont need to login again.
