Jason Dere updated HIVE-8391:
-----------------------------
Attachment: HIVE-8391.1.patch
I think this patch should address this issue - the common class between
timestamp/numeric (up to double) will be treated as double. Are there any Hive
scholars that can confirm that this is the correct behavior?
> Comparion between TIMESTAMP and Integer types goes to STRING as "common
> comparison denominator" instead of a numeric type
