> Currently it's not possible to get at the original InputSplits when using MultipleInputs.
This is because TaggedInputSplit (used by DelegatingInputFormat used by MultipleInputs) is
not public. This means things like the following do not work:
> {code}
> public void map(...) {
>   FileSplit fis = (FileSplit)((TaggedInputSplit) reporter.getInputSplit()).getInputSplit();
>   Path p = fis.getPath();
> }
> {code}
> This prevents users from getting at input split specific data.
