                 Key: MAPREDUCE-1052
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1052
             Project: Hadoop Map/Reduce
          Issue Type: Bug
    Affects Versions: 0.21.0
            Reporter: Dick King
             Fix For: 0.21.0


In my opinion, this was a change for the worse.

I would prefer to bring back the callback interface, at least in addition to the JobInfo interface,
to give API users the option of not creating the whole object if they only want to glean part
of the information.
