bq. * TODO: test the code on a Hadoop 0.20.0 cluster (EC2)
Looks like I'll have to wait till Hadoop 0.20.1 to be able to test on EC2...after creating my own AMI (with a lot of pain, being a noob), I stumbled upon the following bug [HADOOP-5921|http://issues.apache.org/jira/browse/HADOOP-5921]

Don't bother to create an AMI. Use one of the alestic.com AMI's and just
