Review comment:
Actually we did not eliminate anything. If you look closely, what
happened is Reducer 2 and Reducer 3 exchanged names. We still have the same
number of mappers/reducers and the same operators overall. I am not sure why
the names changed however they are arbitrary anyway. So I am not concerned with
that.
