So if I understand correctly, this is an automated system to bring up a hadoop cluster on EC2, import some data from S3, run a job flow, write the data back to S3, and bring down the cluster?
This seems like a pretty good deal. At the pricing they are offering, unless I'm able to keep a cluster at more than about 80% capacity 24/7, it'll be cheaper to use this new service. Does this use an existing Hadoop job control API, or do I need to write my flows to conform to Amazon's API?
