Hi all, I found it confusing that "./spark-ec2 start² actually reinstalls the cluster, which ends up wiping out all the configurations. How about renaming ³start² to ³install² and add a real light-weight ³start² for frequently starting and stopping ec2 instances for mostly cost reasons? The light-weight ³start² can simply bring up the instances and invoke ³bin/start-all.sh². Thoughts?
