Ferdinand Xu commented on HIVE-11504:
-------------------------------------
Thanks [~spena] for your comments. I remove the default constructor since we
can only evaluate the real type for certain column with the help of schema. You
can see that the predicate leaf has a limited type and for float and double,
they should use different builders for parquet.
> Predicate pushing down doesn't work for float type for Parquet
