> Currently, when using "Explain" under Spark mode, it displays dependency information
like this:
> {code}
>  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
> ....
> {code}
> I think it should be improved by giving more information on the dependencies, such as
