Subject [jira] [Commented] (HIVE-9385) Sum a Double using an ORC table
Date Fri, 29 Jan 2016 09:01:39 GMT


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!

>            Priority: Minor
> 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
> If I do the same thing in a textfile table I get a perfectly fine aggregation of the
double field.
