             Summary: CartesianProduct edge won't work with GroupInputEdge
                 Key: TEZ-3654
                 URL: https://issues.apache.org/jira/browse/TEZ-3654
             Project: Apache Tez
          Issue Type: Sub-task
            Reporter: Zhiyuan Yang
            Assignee: Zhiyuan Yang


If a vertex group is used as source of cartesian product, it expands into 
multiple vertices that share the same edge properties and each CP edge is taken 
as individual cartesian product source by CP vertex manager. CP vertex manager 
will find there are more CP edge than expected and abort the AM.  

Ideally group edge semantic should be fixed: both task and vertex manager 
should see same number of sources; also not every edge can be simply duplicated.
