> The following queries do not work:
> Nested filter:
> a = load 'studenttab10k' as (name, age, gpa);
> b = filter a by age < 20;
> c = group b by age;
> d = foreach c { cf = filter b by gpa < 3.0; cp = cf.gpa; cd = distinct cp; co = order
cd by $0; generate group, flatten(co); }
> store d into 'output';
> Nested Distinct:
> a = load '/user/pig/tests/data/singlefile/studenttab10k' as (name, age, gpa);
> b = group a by name;
> c = foreach b { aa = distinct a.age; generate group, COUNT(aa); }
> store c into 'output';
