thanks a lot. it works with the latest version. however, it runs out of 
memory after the 2nd job. what exactly are these jobs? and how many 
should run to finish the task?
(hadoop jar 
-Dmapred.input.dir=testdata/ -Dmapred.output.dir=output)

I have a small cluster, only 5 computers, some of them does not have a 
lot of memory, but the master server should be fine. besides, I only ran 
the test with the smallest movielens data set (100k).
