Modify the number of map tasks
imen Megdiche 2012-12-12, 10:41

I try to force the number of map for the mapreduce job with the command :
  public static void main(String[] args) throws Exception {

          JobConf conf = new JobConf(WordCount.class);
             conf.set("mapred.job.tracker", "local");
         conf.set("fs.default.name", "local");



But it doesn t work.
What can i do to modify the number of map and reduce tasks.

Thank you
