For more information on the Akka clustering, refer to the Akka documentation at http://akka.io/docs/.self_ip:port is the socket address of the Hawk component (Hawk agents, Hawk Console, or Cluster Manager) that is joining the cluster.daemon_ip:port is the socket address of the Cluster Manager acting as a seed node for the TCP Transport Cluster. For the seed node daemon, self_ip:port and daemon_ip:port is same.The Hawk Console subscribes to TCP Transport Cluster membership events. The membership ensures that the console gets notified whenever a new Hawk Agent is up or an existing one is down.ami_tcp_session self_ip:portself_ip:port is the socket address of the Hawk agent acting as the Cluster Manager for the clustertcp_session=self_ip:port agent_ip:ami_tcp_session_portself_ip:port is the socket address for the AMI applicationagent_ip:ami_tcp_session_port is socket address of the Hawk agent AMI component for the TCP Transport Cluster. This is the same socket address that was used in the self_ip:port attribute of the ami_tcp_session parameter in the Hawk agent of the TCP Transport Cluster.
In the Quorum-based strategy of network partitioning, the network partition has to maintain a minimum number of TCP daemons in the TCP Transport Cluster to be operational. This minimum number of daemons is termed as quorum size. In case of network failure, the cluster with the required quorum size remains operational. The TCP Transport Cluster shuts down the other partition and marks any unreachable node in the other partition as down. For example, there are five Cluster Manager in the cluster with quorum size set to three. If the network partition occurs with one partition having three Cluster Managers and other having two then the partition with two Cluster Managers shuts down.
