> For Pandas UDF, the input type for each input argument is Pandas.Series and
> the result type is also of type Pandas.Series. Besides, the length of the
> result should be the same as the inputs. If this is not the case, currently
> the behavior is unclear. We should perform early check for this and provide a
> clear error message.
