Ryan's dashboard

I tried running the Hadoop example at:
http://berkeley-mltea.pbwiki.com/f/ha...

(file comes with a readme) I followed the readme, and attempted to run the example as ryan (myself), hadoop as well as root. I am running Fedora 9 with Sun Java 1.6, and get the following errors:

[ryan@localhost hadoop_example]$ hadoop jar simpleLogReg.jar hadoopml.SimpleLogReg data.txt 10

with the same configuration on Mac OS 10.6, it works fine.
