>
> The NepheleJobGraphGenerator throws a NullPointerException when translating a
> binary union operator. The BinaryUnionPlanNode is not replaced by a
> NAryUnionPlanNode and thus is still treated as a DualInputVertex. Accessing
> the driver code of the BinaryUnionPlanNode causes then the
> NullPointerException.
