--------------------------------

             Summary: Add new configuration kylin.job.mapreduce.min.reducer.number
                 Key: KYLIN-1657
                 URL: https://issues.apache.org/jira/browse/KYLIN-1657
             Project: Kylin
          Issue Type: Improvement
          Components: Job Engine
    Affects Versions: v1.5.1
            Reporter: Dayue Gao
            Assignee: Dayue Gao
            Priority: Minor


We have "kylin.job.mapreduce.max.reducer.number" to limit the max number of reducers for cubing job, but min reducer is hard coded to 1. We should make it also configurable and this could be helpful in some circumstances.
