Reducer should start faster for smaller jobs

                 Key: MAPREDUCE-1463
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1463
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: contrib/fair-share
            Reporter: Scott Chen
            Assignee: Scott Chen

Our users often complain about the slowness of smaller ad-hoc jobs.
The overhead to wait for the reducers to start in this case is significant.
It will be good if we can start the reducer sooner in this case.
