> I tried to turn on Uber AM and put 9223372036854775807l (last char is an L) for maxbytes.  This caused a
> NumberFormatException in the AM and killed it.
> When I try to go to the RM proxy, it redirects me to http://N/A/
> curl -i http://resource.manager.example.com:$port/proxy/application_1326504761991_0001/
> HTTP/1.1 302 Found
> Content-Type: text/plain; charset=utf-8
> Location: http://N/A/
> Content-Length: 0
> Server: Jetty(6.1.26)
> Since the AM has no tracker URL, I would expect the return code to be 400~ or 500~ and return an error.
