Review Comment:
Now I kind of get it. Is this because the local timestamp or
TimestampNTZType is written as Long type in parquet before? Also, there is no
regression micros in schema vs millis in values for TimestampNTZType for
published Hudi releases correct? If so, there is no need for conversion.
