Code below, also attached. I put this together from the word count example.
The problem is with your combiner. When a combiner is specified, it generates the final map output, since combination is a map-side operation. Your combiner takes <Text,IntWritable> generated by your mapper and generates <Text,Text> outputs, which would not be acceptable to your reducer, which accepts <Text,IntWritable> inputs. Does that make sense?
