Gunther Hagleitner commented on HIVE-4320:
------------------------------------------
My apologies. I forgot to include the updates to the golden file for
decimal_udf.q in the patch. HIVE-4320.2.patch has it (if you diff the two
patches you'll see that it's the only change).
> Consider extending max limit for precision to 38

> Max precision of 38 still fits in 128. It changes the way you do math on
> these numbers though. Need to see if there will be perf implications, but
> there's a strong case to support 38 (instead of 36) to comply with other DBs.
