stepExecutionRoleArn

The Amazon Resource Name (ARN) of the runtime role for steps specified in the RunJobFlow request. The runtime role can be a cross-account IAM role. The runtime role ARN is a combination of account ID, role name, and role type using the following format: arn:partition:iam::account-id:role/role-name.

For example, arn:aws:iam::1234567890:role/ReadOnly is a correctly formatted runtime role ARN.

This parameter applies only to steps included in the Steps parameter of this RunJobFlow request. It does not apply to steps added later to the cluster.
