Hi, This may be a silly question, but I'm strangely having trouble finding an answer for it (perhaps I'm looking in the wrong places?).
Suppose I have a cluster with n nodes each with m processors. I wish to test the performance of, say, the wordcount program on k processors, where k is varied from k = 1 ... nm. How would I do this? I'm having trouble finding the proper command line option in the commands manual ( http://hadoop.apache.org/core/docs/current/commands_manual.html) Thank you very much for you time. -SM
