      Description

      Currently when an ApplicationMaster fails the ResourceManager is updating the tracking URL to an empty string, see RMAppAttemptImpl.ContainerFinishedTransition. Unfortunately when the client attempts to follow the proxy URL it results in a web page showing an HTTP 500 error and an ugly backtrace because "http://" isn't a very helpful tracking URL.

      It would be much more helpful if the proxy URL redirected to the RM webapp page for the specific application. That page shows the various AM attempts and pointers to their logs which will be useful for debugging the problems that caused the AM attempts to fail.
