How does system identify multiple nodes as the same cluster?
Hazelcast is a purely distributed and decentralized cluster. Hence there is no master node concept and each member joins a certain cluster somehow. My question is, how does each member identify each other as the same cluster? I know if you specify members ip address in the prconfig.xml file it works but I want to know how system handles this without prconfig.xml, using an empty table (pr_sys_statusnodes). I find "pxClusterID" in the table but is this the one that groups nodes? If so, how is this determined?
