Robert Joseph Evans commented on MAPREDUCE-3706:
------------------------------------------------
OK So now I understand. If org.apache.hadoop.yarn.webapp.Dispatcher.service
catches an exception it tries to set a few cookies, and redirect to the same
page as before. These cookies tell it to render an error page instead of the
regular page, but because the proxy removes all cookies from the requests these
are never set, and they are ignored. We might be able to make this work
properly if we allows cookies to be set between redirects within the proxy.
