Subject Re: Map Reduce over whole row

The WholeRowIterator takes the entire row and encapsulates it in the same
order it was scanned. Because everything is sorted, the columns in teh
WholeRowIterator are maintained in the same order, and the PeekingIterator
does not change this behavior. So you should be fine.
