When a node is joining a cluster, but does not have the correct name of a cluster, the node must stop.
On the hazelcast side the cluster name will be hardcoded to sonarqube. However the defined sonar.cluster.name value will be stored in hazelcast's shared memory.
- When you start the node with an incorrect name first, none of the other nodes can start.
- If you change the cluster name, all the nodes (search nodes included) must be restarted.
