> Project: Hive
> Issue Type: Bug
> Components: Query Processor

>
> Discovered this while investigating why my fix for HIVE-6222 produced diffs.
> I discovered that Decimal128.addDestructive does not adjust the internal
> count when an the number of relevant ints increases. Since this count is used
> in the fast HiveDecimalWriter conversion code, the results are off.
> The root cause is UnsignedDecimal128.differenceInternal does not do an
> updateCount() on the result.
