interface require me to return a Tuple object.
public Tuple getNext() throws IOException {
but the DataBag interface is not a derive class of Tuple so this means I
will need to change the internal code for pig for my loader to return a bag
of tuples. Right?

Hi Pig Users,
I am currently writing a UDF loader. In one of my use case, one line in
the input stream results in multiple tuples. Has anyone encounter or solve
this issue on their end.
The current structure of the code getNext method only return tuple but I
want it to return a List<tuple>. Let me know if there's use case out there
like mine, I am coding it up to return List<tuple> which is more more
flexible than return only one tuple.
Thanks,
John
