M. Pouick commented on HIVE-9385:
---------------------------------

As we experimented the same issue (double sum excessive value in an ORC table). I did some tests. My table was partitionned and bucketed. Changing the bucket's column did nothing. So I re-created the table without the partition and tadaaa ! My sum is now perfectly correct ! 
Hope it helps!

> I’m storing a sales amount column as a double in an ORC table and when I do:
> {code:sql}
> select sum(x) from sometable
> {code}
> I get a value like {{4.79165141174808E9}}
> A visual inspection of the column values reveals no glaring anomalies…all looks pretty normal. 
> If I do the same thing in a textfile table I get a perfectly fine aggregation of the double field.
