Hi, I am using a quad core dual processor machine (i.e. total 8 CPUs). I tried executing the grep example as well as the sort benchmark. In both I could see that only one processor was utilized. I set "mapred.map.tasks" and " mapred.tasktracker.tasks.maximum" values to 8 but still only single processor was utilized. I am interested in setting up both these examples such that maximum CPU utilization occurs. What am I missing?
Thanks, Neeraj
