Subject [jira] [Commented] (HADOOP-7510) Tokens should use original hostname provided instead of ip
Date Mon, 26 Sep 2011 17:09:26 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7510?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13114793#comment-13114793
] 

Nathan Roberts commented on HADOOP-7510:
----------------------------------------

On trunk, we should definitely look at fixing up getCanonicalServiceName(). This method (whether
it be its name, or its javadoc, or its use), has caused significant confusion, which is an
obvious sign it's an interface that needs some rethinking.

> 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.
