I have created EMR default roles by aws emr create-default-roles and then want to create an EMR cluster.
But when I click the "create cluster" button, it says: An error occurred (AccessDeniedException) when calling the RunJobFlow operation: Failed to authorize instance profile arn:aws:iam::011476750252:instance-profile/EMR_EC2_DefaultRole
Do I miss some permissions or did anything else cause this?
Thanks very much.
