Shivaram Venkataraman commented on SPARK-3821:
----------------------------------------------
1. Yes - the same stuff is installed on master and slaves. In fact they have
the same AMI.
2. The base Spark AMI is created using `create_image.sh` (from a base Amazon
AMI) -- After that we pass in the AMI-ID to `spark_ec2.py` which calls
`setup.sh` on the master.
> Develop an automated way of creating Spark images (AMI, Docker, and others)

> Project: Spark
> Issue Type: Improvement
> Components: Build, EC2
> Reporter: Nicholas Chammas
>
> Right now the creation of Spark AMIs or Docker containers is done manually.
> With tools like [Packer|http://www.packer.io/], we should be able to automate
> this work, and do so in such a way that multiple types of machine images can
> be created from a single template.
