> HIVE-6455 optimization uses PreOrder graph walker resulting in double
> invocation of SortedDynPartitionOptimizer(). Because of this there are
> duplicate partitioning columns in RSOp for few test cases (union_remove_17.q
> and similar test cases..)..
> HIVE-6455 optimization does not actually need a PreOrder graph walker. The
> fix is to revert it to DefaultGraphWalker.
