             Summary: Vectorization: Current vector PTF doesn't work under GroupBy and is designed for reduce-shuffle input
                 Key: HIVE-18561

          Components: Hive
            Reporter: Matt McCline

Need to add validation check in Vectorizer that doesn't vectorize unless PTF is under reduce-shuffle (with optional SELECT in-between).
