-----------------------------------
Ben, how much testing did this code go through?
> Pig should be able to split Gzip files like it can split Bzip files

> It would be nice to be able to split gzip files like we can split bzip files.
> Unfortunately, we don't have a sync point for the split in the gzip format.
> Gzip file format supports the notion of concatenate gzipped files. When
> gzipped files are concatenated together they are treated as a single file. So
> to make a gzipped file splittable we can used an empty compressed file with
> some salt in the headers as a sync signature. Then we can make the gzip file
> splittable by using this sync signature between compressed segments of the
> file.
