      Description

      Hi,
      I was using the Chain[Mapper/Reducer] APIs , and in Class Chain line 207 the error thrown :

      "The Mapper output key class does not match the previous Mapper input key class"

      Shouldn't this be "The Mapper input key class does not match the previous Mapper Output key class" ? Sort of misleads
