Amazon EMR service ports
Note
The following are interfaces and service ports for components on Amazon EMR. This is not a complete list of service ports. Non-default services, such as SSL ports and different types of protocols, are not listed.
Important
Use caution when you edit security group rules to open ports. Be sure to add rules that only allow traffic from trusted and authenticated clients for the protocols and ports that are required to run your workloads.
