Abhishek Modi commented on YARN-8155:
-------------------------------------
{quote}Catching notfoundexception and converting into web application exception
changing return code. We should still retain return code not found right?
{quote}
I don't think we should pass WebApplicationException with Not Found code as
that is meant when web application doesn't handle that page request. IMO
WebApplicationException should be passed only with Internal Error only.
