Sorry for having made you confused. I mean, if you have explicitly specify the reduce task number in your hadoop conf/mapred-site.xml or some where else, PFP would only execute one reduce task. Your parameter groups 10 would only make PFP call reduce method 10 times. Actually reduce method had been called 10 times with a single reduce task.
