> 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 :)
