---------------------------------------------------------------------
So I am using a UDF which extends AggregateFunction<T, ACC>. For that we
implement createAccumulator, getValue, accumulate and merge method. When you
create accumulator of type java.util.Set, the UDF fails giving error Error
inferring type logic. But when at the same point I use java.util.List, it works
fine.
I also tried with @DatatypeHint but it still gives the same error.
