{code}
One = load 'one.txt' using PigStorage() as ( one: int );
LabelledTupleInBag = foreach One generate { ( 1, 2 ) } as mybag { tuplelabel:
tuple ( a, b ) };
AnonymousTupleInBag = foreach One generate { ( 2, 3 ) } as mybag { tuple ( a, b

Tuples = union LabelledTupleInBag, AnonymousTupleInBag;
dump Tuples;
