As a follow up, this is not peculiar to my programs but hadoop ones too:
I started the cluster as (using Fedora AMI and c1.medium)
hadoop-ec2 launch-cluster --env REPO=testing --env HADOOP_VERSION=0.20 test2 1
and error is [1]
But it works(and so do my programs) if I launch a cluster with e.g. 4
nodes as opposed to 1.
