> A DAG created by OperatorGraph is not equal to the corresponding DAG that is 
> submitted to Tez.
> Because of this problem, ParallelEdgeFixer reports a pair of normal edges to 
> a parallel edge.
> We observe this problem by comparing OperatorGraph and Tez DAG when running 
> TPC-DS query 71 on 1TB ORC format managed table.
