------------------------------------------

I think this is fixed in Spark 1.5?

>             Project: Spark
>          Issue Type: Bug
>          Components: SQL
>    Affects Versions: 1.4.1

> If we have this query:
> {code}
> SELECT IF(column > 1, 1, NULL) FROM T1
> {code}
> On Spark 1.4.1 we have this:
> {code}
> override lazy val resolved = childrenResolved && trueValue.dataType == falseValue.dataType
> {code}
> So if one of the types is NullType, the if expression is not resolved.
