Hi Jonathan,

Sorry you're having issues. Are you able to consistently reproduce this
issue? Also which AMI are you using? I would also try the 'restart'
command which will reboot all instances and reconfigure the cluster.

When I try to start the cluster everything works fine, it starts up two m1.small instances in my EC2 account, and successfully goes through the whole startup, until it gets to Configuring passwordless ssh for root, and then stops, and stays there indefinitely (I stopped it after 45 minutes and terminated the cluster)
