Yin Huai commented on SPARK-8828:
---------------------------------

We also need to take a look at if we need CombinSum (introduced by SPARK-5680). If not, we can also remove the change of https://issues.apache.org/jira/browse/SPARK-6451.

> SPARK-5680 introduced a bug to sum function. After this change, when there is no input to a sum function (or all input values are nulls), it returns 0.0 instead of null, which is wrong.
