Nicholas Chammas commented on SPARK-3821:
-----------------------------------------
If you want Java 8 alongside 7, you can install both to separate paths. For
spark-ec2's purposes, we only need 7.
The AMIs used as the base are [defined in the Packer
template|https://github.com/nchammas/spark-ec2/blob/0f313de64ad9542d1a0f0d6f27131ca4bc01d8c3/image-build/spark-packer-template.json#L5-L6].
The generated AMIs do not include Spark itself--just its dependencies, plus
related tools for spark-ec2.
> Develop an automated way of creating Spark images (AMI, Docker, and others)

>
> 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.
