Description

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 ) }; -- Anonymous tuple creates bug

Tuples = union LabelledTupleInBag, AnonymousTupleInBag;

dump Tuples;

Why can't there be an anonymous tuple at the top level of a bag?
