Ashutosh Chauhan commented on HIVE-19160:
-----------------------------------------
{code}
Decimal lowValue = aggregateData.getLowValue() != null &&
aggregateData.getLowValue().compareTo(newData.getLowValue())
> 0 ?
aggregateData.getLowValue() : newData.getLowValue();
{code}
should be
{code}
Decimal lowValue = aggregateData.getLowValue() != null &&
aggregateData.getLowValue().compareTo(newData.getLowValue())
> 0 ?
newData.getLowValue() :aggregateData.getLowValue();
{code}
Since we get a new value which is lower, that is what we want to use and
persist in stats.
