Subject [jira] [Commented] (MAPREDUCE-3706) HTTP Circular redirect error on the job attempts page
Date Mon, 27 Feb 2012 21:57:49 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-3706?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13217613#comment-13217613
] 

Robert Joseph Evans commented on MAPREDUCE-3706:
------------------------------------------------

OK So now I understand.  If org.apache.hadoop.yarn.webapp.Dispatcher.service catches an exception
it tries to set a few cookies, and redirect to the same page as before.  These cookies tell
it to render an error page instead of the regular page, but because the proxy removes all
cookies from the requests these are never set, and they are ignored.  We might be able to
make this work properly if we allows cookies to be set between redirects within the proxy.
