> The wikipedia ingest Map job uses a derivative of the FileInputFormat, which launches
one job per file. Given the partitioning strategy and workload distribution, it makes sense
to launch multiple mappers per file. Each mapper can then take a chunk of the articles in
the file using the same partitioning strategy as the assignment of row IDs.
