Hello all, In my understanding, mapred.tasktracker.tasks.maximum is ued to decide how many tasks should be allocated simultaneously per tasktracker. My problem is I would like to set this parameter individually for each tastracker, each one telling a job tracker how many tasks that node can deal with simultaneously (my tasks are extremely CPU and memory intensive), so the number would be a function of the number of CPUs, number of other processes running, amount of memory etc....
Is that something that hadoop supports? Is that something that we could implement and contribute back? Any interest in this functionality? Thanks, Lorenzo Thione Powerset, Inc.
