Have you restarted your cluster ?

You can actually specify this parameter in JobConf.
See the usage:
        TaskLog.cleanup(job.getInt("mapred.userlog.retain.hours", 24));
./src/mapred/org/apache/hadoop/mapred/Child.java

This parameter effects JobTrackers and TaskTrackers so you also
restart the wrong hadoop components.
