Tuples in UDF and null
If I define and set tuple like this:

Tuple t1 = mTupleFactory.newTuple(2);
t1.set(0, "Hello");
t1.set(1, NULL);

and have schema like:

b:bag{t:tuple(a:chararray, b:chararray)

and then in the pig script if I do:

page = foreach B generate b;

What should be expected outcome? Would "generate" convert NULL into literal
'NULL' as a string? Or does it skip over that NULL.
