Chain APIs error misleading
---------------------------

                 Key: MAPREDUCE-1242
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-1242
             Project: Hadoop Map/Reduce
          Issue Type: Bug
            Reporter: Amogh Vasekar
            Priority: Trivial


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 :)
