Subject [jira] [Commented] (HADOOP-7510) Tokens should use original hostname provided instead of ip
Date Fri, 23 Sep 2011 21:17:26 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7510?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13113773#comment-13113773

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.
