Subject [jira] [Commented] (HADOOP-7510) Tokens should use original hostname provided instead of ip
Date Mon, 19 Sep 2011 18:05:09 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7510?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13108032#comment-13108032

Jitendra Nath Pandey commented on HADOOP-7510:
----------------------------------------------

Please remove the rack related change in MiniDFSCluster. That doesn't seem necessary. It will
be surprising if some tests break without that change, and might indicate some other bug.

Patch looks good to me otherwise.

> 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.
