Subject Re: Sorting the inputSplits

Can you clarify the requirement "processed first"? Maps run in parallel
without any ordering guarantees. If you want to affect the mapping
file->split number, you can implement your own getSplits in the custom
input format and return splits ordered anyway your like.
