Chao updated HIVE-7607:
-----------------------
Description:
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 work information and edge type.
