Just curious, would you be able to use Spark on EMR rather than on EC2? Spark on EMR will handle lost nodes for you, and it will let you scale your cluster up and down or clone a cluster (its config, that is, not the data stored in HDFS), among other things. We also recently announced official support for Spark on EMR: http://aws.amazon.com/emr/spark
