> 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.
