Hi,
@Fabian: Are you sure that is the case? I don't think that the annotations
are set correctly automatically at the moment. There is a pullrequest open,
but it was not yet merged.
Your UDF looks like field 1 of the first tuple input is also constant:
@ConstantFieldsFirst("1->1;2 -> 2")
@ConstantFieldsSecond("0 -> 0")
Regards,
Sebastian
