Hi, all,I have configured "mapred.map.tasks" and "mapred.reduce.tasks" in mapreduce.xml to "32"(see below), but Hadoop uses only 2 or 3 tasks when running a job(I see it from the http://nutch03:50030/jobtracker.jsp "Map Total" column and "Reduce Total" column). How can I let Hadoop use more tasks so it can run faster?<property> <name>mapred.map.tasks</name> <value>32</value> <description>define mapred.map tasks to be number of slave hosts</description></property><property> <name>mapred.reduce.tasks</name> <value>32</value> <description>define mapred.reduce tasks to be number of slave hosts</description></property> Dennis
