> It would be good to change NNBench a bit
> - numberOfFiles is actually number of files per mapper. It would be good to document
it
> - right now, we have to kick off separate jobs for each operations. Since we operate
on same generated files, it would be good to have an option of all operations or chain selected
operations
> - It would be good to see if we can kick off all operations in parallel to simulate the
usual NameNode state
