Subject [jira] [Commented] (HADOOP-8459) make SecurityUtil.setTokenServiceUseIp method public
Date Thu, 31 May 2012 20:52:23 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8459?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13286922#comment-13286922
] 

Daryn Sharp commented on HADOOP-8459:
-------------------------------------

To elaborate: consider the case of the client gets a token from "httpfs.domain" which is a
CNAME to "host1234.domain".  The server can't know the host name the client used, so it would
stamp "host1234.domain" into the token.  When the client tries to re-establish a connection
to "httpfs.domain" it won't find a token with that hostname, hence why the client is responsible
for setting the service.
