Amazon EMR Management Guide Working With Amazon EMR-Managed Security Groups Amazon EMR-Managed Security Group for Core and Task Instances (Public Subnets) The default managed security group for core and task instances in public subnets has the Group Name of ElasticMapReduce-slave . The default managed security group has the following rules, and Amazon EMR adds the same rules if you specify a custom managed security group. Type Protocol Port Range Source Details Inbound rules All ICMP- IPV4 All N/A All TCP TCP All All UDP UDP All The Group ID of the managed security group for core and task instances. In other words, the same security group in which the rule appears. These reflexive rules allow inbound traffic from any instance associated with the specified security group. Using the default ElasticMapReduce-slave for multiple clusters allows the core and task instances of those clusters to communicate with each other over ICMP or any TCP or UDP port. Specify custom managed security groups to restrict cross-cluster access. All ICMP- IPV4 All N/A All TCP TCP All All UDP UDP All The Group ID of the managed security group for the master instance. These rules allow all inbound ICMP traffic and traffic over any TCP or UDP port from any master instances that are associated with the specified security group, even if the instances are in different clusters.

Type Protocol Port Range Source Details Inbound rules All ICMP- IPv4 All N/A All TCP TCP All All UDP UDP All The Group ID of the managed security group for the master instance. In other words, the same security group in which the rule appears. These reflexive rules allow inbound traffic from any instance associated with the specified security group and reachable from within the private subnet. Using the default ElasticMapReduce-Master-Private for multiple clusters allows the core and task nodes of those clusters to communicate with each other over ICMP or any TCP or UDP port.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
