I found that the logs infos from the Nutch classes, seems to go into
hadoop-nutch-tasktracker-nodename.log.
It looks like hadoop wrap the nutch logs, the output is like this:
2007-05-10 10:36:33,142 INFO  mapred.TaskRunner - task_0005_m_000000_0
fetching http://apache.org/

But I still have at max only the INFO level, even adding some rules like
this in the log4j.properties
log4j.logger.org.apache.hadoop.mapred.TaskRunner=DEBUG
