Sergio Peña commented on HIVE-8745:
-----------------------------------
I agree using compareTo() on HiveDecimal.
Hive used to trim trailing zeroes before, so the equals() validation was always
correct. Now, with the new change we should allow users to compare decimal
values as before.
What do you think [~xuefuz]?
> Joins on decimal keys return different results whether they are run as reduce
> join or map join
