Ravi Prakash commented on YARN-465:
-----------------------------------

Thanks for the updates and answers Andrey!
I could not find a WebAppProxy.start() method. I don't see the problem in 
calling the main method from tests. I would prefer that more than changing 
src/main code to suit tests. Removing the proxy.join() method makes the main() 
thread not wait for the proxy server thread to exit. I guess that could also be 
another way to do things but I am just wary of changing src/main code without 
good reason for the purpose of writing unit tests.
Please correct me if I am wrong, port will always be 0 at the time it is being 
printed out in the last Log.info in the start() method.
I am satisfied with the other changes. Thanks a lot for them. I am not going to 
be a stickler for the above issues, so I'm going to give the trunk patch a +1.
branch-2 still has the "answer=3" option, and maybe we can add it to trunk or 
remove it from branch-2. What do you think?
