Owen O'Malley commented on HIVE-11504:
--------------------------------------
If you need to differentiate the types for parquet, please do that in the
parquet bindings and not in the generic api. Hive of course gives you the
precise types so the input format has the necessary information already.
> Predicate pushing down doesn't work for float type for Parquet
