> I'm trying to build a Kylin Cube that will get me the Average of a SmallInt
> nullable column Col1. I expect any null value to not be counted towards this
> average. When I work on my table in Hive this is exactly the result that I'm
> getting when applying the AVG function. However when I build the cube in
> Kylin on top of this table all the null values in my measurements columns are
> becoming zeros and then counted towards the calculation of the AVG. Is there
> a way to force Kylin to treat nulls as nulls?
