I've tried that... using this recipe with c1.xlarge:
-------
whirr.cluster-name=hadoop
whirr.instance-templates=1 hadoop-namenode+hadoop-jobtracker,18
hadoop-datanode+hadoop-tasktracker
whirr.instance-templates-max-percent-failures=100
hadoop-namenode+hadoop-jobtracker,70
hadoop-datanode+hadoop-tasktracker
whirr.max-startup-retries=1
whirr.provider=aws-ec2
whirr.identity=${env:AWS_ACCESS_KEY_ID_LIVE}
whirr.credential=${env:AWS_SECRET_ACCESS_KEY_LIVE}
whirr.hardware-id=c1.xlarge
whirr.location-id=us-east-1
whirr.image-id=us-east-1/ami-1136fb78
whirr.private-key-file=${sys:user.home}/.ssh/whirr
whirr.public-key-file=${whirr.private-key-file}.pub
whirr.hadoop.version=0.20.204.0
whirr.hadoop.tarball.url=http://archive.apache.org/dist/hadoop/core/hadoop-${whirr.hadoop.version}/hadoop-${whirr.hadoop.version}.tar.gz

The cluster started up this time, however I see this exception in the Whirr log:
malformed image: null

I run the proxy as usual and try to connect to the Namenode UI or
Jobtracker UI.
It connects but I see an empty page... it usually works fine.
Am I hitting another problem?
Thanks,
Paolo
