Parquet vectorization support was added in 2.2.0. In order to enable it you
should set hive.vectorized.execution.enabled=true. Following other configs
are also relevant for vectorization and you should have them enabled as
well.

hive.vectorized.use.vector.serde.deserialize=true;
hive.vectorized.execution.reduce.groupby.enabled=true;
hive.vectorized.execution.reduce.enabled=true;
