Amazon EMR service limits can now be managed through AWS Service Quotas

By GIXnews

You can now use AWS Service Quotas to view and manage your Amazon EMR service limits, also known as quotas, from a central location via the AWS console, API, or AWS CLI. Using AWS Service Quotas, you can view your service limits in one place and eliminate the need to go to multiple sources or maintain your own list.
