I am combining two questions here. I have setup a cluster using cloudera manager on aws using the cloudera manager classic setup wizard. My questions are 

1. How do I automate the setup of the cluster right from ec2 instance creation and startup all the way to a working cloudera cluster with hdfs, hbase, MR, zookeeper services running and ready for data processing?

2. Whether or not question 1 is feasible, assuming that I have a running cluster and additional ec2 nodes up and running, is it possible to programmatically add these new nodes to the existing cluster?
