Subject [jira] [Commented] (MAPREDUCE-4064) Job History Link in RM UI is redirecting to the URL which contains Job Id twice
Date Tue, 27 Mar 2012 14:16:30 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4064?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13239488#comment-13239488
] 

Robert Joseph Evans commented on MAPREDUCE-4064:
------------------------------------------------

Having the changes only apply when doing a redirect will fix the problem for Map Reduce, but
I think the underlying cause of the issue is not with the proxy itself.  I believe that the
proxy is working as designed, the problem is with the code that is producing the URI.

I believe that the issue is with ProxyUriUtils.getProxyUri().  It is adding on the extra path
part that should be removed.  It should always act as if the trackingUri parameter is null.
 And if that is the case that parameter should just be removed, which will simplify things
in RMAppAttemptImpl.java because we will not have to ever regenerate the proxiedTrackingUrl.

I am fairly sure that I put this bug in so thank you for finding it and trying to fix it.
