> HIVE-16222 introduced row.serde.inputformat.excludes setting to disable row.serde for specific NON-Vectorized formats.
> Since MapredParquetInputFormat is currently natively vectorized it should be removed from that list.
> Even when hive.vectorized.use.vectorized.input.format is DISABLED
> Vectorizer will not vectorize in row deserialize mode if the input format has is natively Vectorized so it is safe to remove.
> Conf order to control vectorization:
> 1. hive.vectorized.use.vectorized.input.format
> 2. hive.vectorized.use.vector.serde.deserialize
> 3. hive.vectorized.use.row.serde.deserialize
