You now have the ability in the AWS Command Line Interface (CLI) to set values in the AWS CLI configuration file for several HAQM EMR commands. You can set these parameters once, instead of specifying them with each command. In the HAQM EMR create-cluster command, you can now set variables for the HAQM EMR service role, HAQM EC2 instance profile, SSH key name, enable debugging, and Log URI bucket in HAQM S3. You can also set the variable for local key pair location in these HAQM EMR commands: SSH, get, put, and socks.
Using the HAQM EMR create-default-roles command, you can easily create and use default AWS Identity and Access Management (IAM) roles for your cluster’s HAQM EMR service role and EC2 instance profile. We have enhanced this command to automatically set the default HAQM EMR service role and EC2 instance profile values for their respective variables in the create-cluster command, so you do not need to specify them manually after they are created.
