> Key: SPARK-18048

> Project: Spark

> If expression behaves differently if true and false expression are
> interchanged in case of different data types.
> For eg.
> checkEvaluation(
> If(Literal.create(true, BooleanType),
> Literal.create(identity(1), DateType),
> Literal.create(identity(2L), TimestampType)),
> identity(1)) is throwing error while
> checkEvaluation(
> If(Literal.create(true, BooleanType),
> Literal.create(identity(1L), TimestampType),
> Literal.create(identity(2), DateType)),
> identity(1L)) works fine.
> The reason for the same is that the If expression 's datatype only considers
> trueValue.dataType.
> Also,
> checkEvaluation(
> If(Literal.create(true, BooleanType),
> Literal.create(identity(1), DateType),
> Literal.create(identity(2L), TimestampType)),
> identity(1))
> is breaking only in case of Generated mutable Projection and Unsafe
> projection. For all other types its working fine.
> Either both should work or none should work
