Gunther Hagleitner commented on HIVE-4327:
------------------------------------------
Actually it's the other way around. I don't have to update the UDAFs. Fixed it
now the same way other types work.

> The query:
> SELECT dec * cast('123456789012345678901234567890.1234567' as decimal) FROM
> DECIMAL_PRECISION LIMIT 1
> fails with an NPE while constant folding. This only happens when the decimal
> is out of range of max precision.
