> We have special {{PartiallyRawComparator}} interface which provides nice speedup by removing unnecessary objects deserializations during insert into result multi-map. And we have a one implementation for now for {{Text}} class: {{TextPartiallyRawComparator}}.
> We should do the following:
> 1) Try guessing proper comparator in runtime using {{JobConf.getOutputKeyClass()}} property. 
> 2) Add ability to disable this automatic resolution.
