  job.setOutputKeyClass(Text.class);
job.setOutputValueClass(IntWritable.class);

Does this mean the input to the reducer should be Text/IntWritable or 
the output of the reducer is Text/IntWritable?

What is the inverse of this.. setInputKeyClass/setInputValueClass? Is 
this inferred by the JobInputFormatClass? Would someone mind briefly 
explaining?

Thanks
