      Description

      Currently, when using "Explain" under Spark mode, it displays dependency information like this:

       STAGE PLANS:
        Stage: Stage-1
          Spark
            Edges:
              Reducer 2 [org.apache.hadoop.hive.ql.plan.SparkWork$Dependency@29a09c49, org.apache.hadoop.hive.ql.plan.SparkWork$Dependency@6f7491f8]
            DagName: chao_20140804145151_acc57d5a-27fa-44c0-aabc-052b318ed832:2
      ....
      

      I think it should be improved by giving more information on the dependencies, such as work information and edge type.
