Carl Steinbach updated HIVE-436:
--------------------------------
Component/s: UDF
> MIN and MAX should inherit type
> -------------------------------
>
> Key: HIVE-436
> URL: https://issues.apache.org/jira/browse/HIVE-436
> Project: Hive
> Issue Type: Wish
> Components: UDF
> Reporter: Adam Kramer
>
> MIN and MAX functions currently return the DOUBLE type...but really, they
> should return the same type as the column they operate on.
> In some cases like SUM, it's possible that the result would overflow making
> DOUBLE more useful as it can drop digits and swap to scientific notation, but
> MIN and MAX by definition cannot have this problem because the answers are
> always represented in the column they are run across.
> Easy workaround: CAST all of my MINs and MAXes. It's just a wish.
