What's the current status on adding slaves to a running cluster? I want to leverage spark-ec2 and autoscaling groups. I want to launch slaves as spot instances when I need to do some heavy lifting, but I don't want to bring down my cluster in order to add nodes.
Can this be done by just running start-slave.sh?? What about using Mesos? I just want to create an AMI for a slave and on some trigger launch it and have it automatically add itself to the cluster. thanks
