Subject sum a double in ORC bug?
Date Thu, 15 Jan 2015 02:42:30 GMT
*Hive 13

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

I couldn't find anything like this already reported so I filed a bug (9385).
