Amruth S commented on HIVE-9385:
--------------------------------
We are using hive 1.2.1 and facing the same issue. I feel this is related to
vectorisation. If I disable vectorization, I get the exact sum on a double
column.
Is this bug occuring in hive 2.0 also?
> Sum a Double using an ORC table
> -------------------------------
>
> Key: HIVE-9385
> URL: https://issues.apache.org/jira/browse/HIVE-9385
> Project: Hive
> Issue Type: Bug
> Affects Versions: 0.13.1
> Environment: HDP 2.x, Hive
> Reporter: Nick Martin
> 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 normal.
> If I do the same thing in a textfile table I get a perfectly fine aggregation
> of the double field.
