             Summary: Spark "Explain" should give useful information on 
dependencies
                 Key: HIVE-7607
                 URL: https://issues.apache.org/jira/browse/HIVE-7607
             Project: Hive
          Issue Type: Improvement
          Components: Spark
            Reporter: Chao


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.
