Hi, I have seen that restarting the mapreduce daemons is enough in that case (stop-mapred and start-mapred). In fact, if you change just the properties relevant only to tasktracker, you just need to restart the tasktracker on each node or that specific node where you want the change to take effect. (e.g map.tasks.maximum etc.)
