Subject [jira] [Commented] (HADOOP-7510) Tokens should use original hostname provided instead of ip
Date Fri, 16 Sep 2011 15:38:09 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7510?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13106531#comment-13106531
] 

Owen O'Malley commented on HADOOP-7510:
---------------------------------------

I agree with Jitendra about removing the change to the higher level objects (JobClient and
NameNode) instead of the rpc proxies.

Remove both of the FIXME comments, since neither is relevant.

Don't set the service in DistributedFileSystem, since the tokens from DFSClient must be equivalent,
which also means you don't need the new namenode field.

> 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.
