> {{setKeyGroupingComparator(final RawComparator<K2> groupingComparator)}} and {{setKeyOrderComparator(final RawComparator<K2> orderComparator)}} are both using the {{K2}} generic which is the "The reduce output key type".
> Its probably just a c&p oversight since the same methods are present in the MapReduceDriverBase class. Here the generic {{K2}} is the mapper output key though.
