Ability to take a picture of an AWS EMR cluster or name

I am new to AWS and have tried some use cases. I want to create EMR clusters on demand with some predefined configurations and installed applications / scripts. I planned to first create a snapshot of an existing EMR cluster, or at least a namenode, and then use it every time I want to create other clusters. But after some Google search, I could not find a way to capture the EMR cluster snapshot. Can I create a snapshot? or any other alternative way that might help me in my use case.

Appreciate any help.

thanks

It is not possible to create a snapshot of an EMR node cluster, and you cannot use a custom AMI when starting the cluster. However, you can install the software on the cluster nodes during the creation of the cluster using custom download actions. You can create your own boot scripts and use them each time you start a new cluster. This way you can achieve similar functionality with the one you are looking for.

For more information using download operations for EMR, visit: http://docs.aws.amazon.com/ElasticMapReduce/latest/DeveloperGuide/emr-plan-bootstrap.html#bootstrapCustom
