[jira] [Created] (HIVE-9385) Sum a Double using an ORC table

Nick Martin created HIVE-9385:
---------------------------------

             Summary: 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:

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.
