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