So I wrote my first org.apache.hadoop.madpreduce.Job (not ...mapred.Job). Oddly enough, when the reducer is invoked, the "Iterable values" parameter actually iterates over just one value, not all the corresponding values that were output by my map tasks. I know this from adding calls to System.out.println to my map and reduce code. I also know that my combiner was not invoked (also from println debugging). So now I am trying to determine why things are not being wired up correctly. What is the right way to debug situations like this?
