Easy way to start cluster with Java 1.8?

[adamdossa]

Scripts work great, but EC2 machines have Java 1.7 on them rather than Java 1.8.

I can see #12 adds some functionality related to this, but it's not clear to me exactly how to take advantage.

Do I need to build a new AMI and pass this on the command like (--ami) rather than using the versions defaulted from ami-list in the repo? Is there anywhere documented the exact process to build this new AMI? I can see the create_image.sh script, but usage isn't entirely clear to me.

Thanks!

Short of recreating the AMIs there might not be an out of the box way to do this. However we can just install OpenJDK 8 using something like yum install java-1.8.0-openjdk-devel.x86_64 on the machines ? If that works we can do it during initialization.
