> 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.
