Ferdinand Xu commented on HIVE-11504:
-------------------------------------
Thanks for your review [~owen.omalley] and your clarification [~spena].
Parquet uses the Hive search argument to construct its predication and it
treats float/double and int/long as different types. So we have to pass in with
its original types. You can find detailed information in HIVE-8122. I think
this patch should have no impact since it's converted to double type finally in
the method RecordReaderImpl#getBaseObjectForComparison. Feel free to let me
what's your thoughts.
