I have one master and 6 slaves. By looking the each slaves logs I've noticed that REDUCE operation just runs on one machine. So does that mean that reduce just runs on one machine ? And if that is true how can I specify that I want the reduce to run also on the other machines ? Thanks for any help, Jean-Pierre.
