kangkaisen commented on KYLIN-2744:
-----------------------------------
Thanks liyang and Billy for your comment.
I think the column type and sum measure type should be same in web, and
back-end use current Ingester and Aggregator handle sum measure, and the final
result will consistent with Presto and Hive. which is reasonable, user-friendly
and easy.
As for the sum for double type is not fully precise，If user want to get fully
precise result, user should use decimal type in Hive.
> Should return correct type for SUM measure in web
