Hi, The EC2 documents<http://spark.incubator.apache.org/docs/0.8.1/ec2-scripts.html>has a section called 'Running Applications', but it actually lacks the step which should describe how to run the application.
The spark_ec2 script<https://github.com/apache/incubator-spark/blob/59e8009b8d5e51b6f776720de8c9ecb09e1072dc/ec2/spark_ec2.py>seems to set up a standalone cluster, although I'm not sure why AMI_PREFIX point to mesos ami list<https://github.com/apache/incubator-spark/blob/59e8009b8d5e51b6f776720de8c9ecb09e1072dc/ec2/spark_ec2.py#L44> . Assuming that the cluster type is standalone, we could run the app by spark-class script. Is this the missing step in the documentations? spark-class script does not launch a daemon, is it suppose to be used with nohup for long running applications? Finally, is the standalone cluster type used for real world applications, or do people use spark on yarn and mesos when it comes to production?
