             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 0.23.0, 0.24.0
            Reporter: Robert Joseph Evans
            Assignee: Robert Joseph Evans
            Priority: Critical
             Fix For: 0.24.0, 0.23.1


There are several places in the web apps where an error condition should short circuit the page from rendering, but it does not.  Ideally the web app framework should be extended to support exceptions similar to Jersey that can have an HTTP return code associated with them.  Then all of the places that produce custom error pages can just throw these exceptions instead.
