> 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.
