Subject [jira] [Commented] (MAPREDUCE-3436) jobhistory link may be broken depending on the interface it is listening on
Date Mon, 05 Dec 2011 19:58:40 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3436?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13162985#comment-13162985
] 

Bruno Mahé commented on MAPREDUCE-3436:
---------------------------------------

Does that mean a user cannot have this service listen on all interfaces without breaking the
ui?

But that would also mean the jobhistory link is broken by default, unless its config is updated
by the user to point to the correct ip/hostname.
I also don't understand why other web ui links are able to figure out the right hostname/ip
by themselves without any extra configuration. I haven't had time to figure out how it's done
exactly, but the jobhistory is the only place where such configuration is needed.
