> The last split generated by FileInputFormat.getSplits considers
> {{blkLocations.length-1}} to be the hosts for the split.
> The last split may be larger than the rest (SPLIT_SLOP=1.1 by default) - in
> which case locality is picked up from a smaller block.
> e.g. 1027MB file with a 128MB split size. The last split ends up being 131MB.
> The hosts for locality end up being the nodes containing the 3MB block
> instead of the 128MB block.
