Moving the thread to mapreduce-user mailing list. Are you passing a new api mapper? If you are passing a new api mapper, and wants to use MultipleInputs, it is not supported in branch 0.20. MultipleInputs are ported to use new api from branch 0.21. Until 0.21 is released, you might have to use old api mapper.

But looks like InputFormat class is mandatory for MultipleInputs.addInputPath. How to correct it? Is there any alternatives? Thanks,
