> UDFFinder doesn't look into POCast so it will miss LoadFunc used by POCast for lineage.
We could see "class not found" exception in some cases. Here is a sample script:
> {code}
> a = load '1.txt' using CustomLoader() as (a0, a1, a2);
> b = group a by a0;
> c = foreach b generate flatten(a);
> d = order c by a0;
> e = foreach d generate(a1+a2);  -- use lineage
> dump e;
> {code}
