Kihwal Lee commented on HADOOP-7510:
------------------------------------

I finished reviewing the code and thought it was good, but after seeing Jitendra's comment I decided to wait for Daryn's response.  Having read his justification, I think it is quite reasonable. So I feel good about this patch again. :)

I've been following the discussion around delegation token. It seems there are some areas that can be improved and there are many ways of doing them. I think this patch is a reasonable compromise.

> Tokens currently store the ip:port of the remote server.  This precludes tokens from being used after a host's ip is changed.  Tokens should store the hostname used to make the RPC connection.  This will enable new processes to use their existing tokens.
