No, the line in the book is correct. I was trying to use another one command line (See in the first post). I think it was not working because of some _HOME issues which are deprecated.
I'm now using thsi command line and it's working fine (except for the number of tasks). HADOOP_CLASSPATH=`/home/hbase/hbase-0.94.0/bin/hbase classpath`:`/home/hadoop/hadoop-1.0.3/bin/hadoop classpath` /home/hadoop/hadoop-1.0.3/bin/hadoop jar /home/hbase/hbase-0.94.0/hbase-0.94.1.jar rowcounter -Dhbase.client.scanner.caching=100 -Dmapred.map.tasks=6 -Dmapred.map.tasks.speculative.execution=false work_proposed I simply don't know if the -D parameters are taken into consideration since I get the same results (numbers of tasks, time of exec, etc.) with and without them.
