Ferdinand Xu commented on HIVE-18397:
-------------------------------------
I think Parquet doesn't support interval_day_time type since write path does
not support it as shown in the code you mentioned.
> Support vectorization for INTERVAL_DAY_TIME type

> Vectorizer currently assumes that all the primitives are supported for a
> inputformat which implements {{VectorizedInputFormatInterface}}. Currently
> any table which has timestamp or interval_day_time type will fail execution
> in vectorized mode. HIVE-18323 adds support for timestamp. We should also add
> support for interval_day_time.
