[Hive] for a 2-stage map-reduce job, number of reducers not set correctly
-------------------------------------------------------------------------

                 Key: HADOOP-4356
                 URL: https://issues.apache.org/jira/browse/HADOOP-4356
             Project: Hadoop Core
          Issue Type: Bug
          Components: contrib/hive
            Reporter: Namit Jain
            Assignee: Namit Jain


the number of reducers are always set to the default. In a group-by statement, this leads
to so many redundant reducers for the 2nd map-reduce job
