EMR provides AWS CLI export using the console.

You will then get a single line of AWS CLI to create a cluster with the same settings.

However, there is no API for command line tool. So this code is making AWS CLI for create-cluster programmatically.

• At first, it works parsing the parameters from “aws cli describe-cluster”.
• And then it creates a parameter string to be appended after "aws cli create-cluster".
• Example:

aws emr create-cluster --auto-scaling-role EMR_AutoScaling_DefaultRole \
--applications Name=Spark Name=Hadoop Name=Hive \
--ebs-root-volume-size 10 \
--ec2-attributes ... \
--service-role EMR_DefaultRole \
--release-label emr-5.25.0 \
--name 'test-emr-2019-08-04' \
--instance-groups ... \
--scale-down-behavior TERMINATE_AT_TASK_COMPLETION \
--region ap-northeast-2
