Lefty Leverenz commented on HIVE-9385:
--------------------------------------

[~nimartin], somehow two issues got created for this (HIVE-9384 and HIVE-9385).

>                 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:
> select sum(x) from sometable
> 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.
