Robert Joseph Evans commented on MAPREDUCE-2665:
------------------------------------------------

I am a bit confused by the changes, and it might just be me so if you could 
clarify a few things I would appreciate it.

Doesn't NetUtils.getHostname() just return the name of the host we currently 
are on, and doesn't WebApp.getPort() just return the port number that the web 
app is listening on and we currently are to thorough the web browser?  If so 
why are these changes needed at all because I am already connected to that box 
on that port.  I can just grab it from the browser address bar?  Unless of 
course this is actually going through a proxy of some sort.
