Name of the service role for the EMR cluster that you create. The role must have sufficient permissions to create a cluster, access S3 resources, and run jobs on the cluster.
When the AWS administrator creates this role, they select the “EMR” role. This contains the default AmazonElasticMapReduceRole policy. You can edit the services in this policy.
EC2 Instance Profile
Name of the EC2 instance profile role that controls permissions on processes that run on the cluster.
When the AWS administrator creates this role, they select the “EMR Role for EC2” role. This includes S3 access by default.
Auto Scaling Role
Required if you configure auto-scaling for the EMR cluster.
This role is created when the AWS administrator configures auto-scaling on any cluster in the VPC.
Default: When you leave this field blank, it is equivalent to setting the Auto Scaling role to “Proceed without role” when the AWS administrator creates a cluster in the AWS console.
