There is no real master in Hazelcast clusters. The oldest node plays some kind of a special role so you can imagine this one as the "master".

To get this node get retrieve the first element from the memberlist.

Cluster cluster = hazelcastInstance.getCluster();
Set<Member> members = cluster.getMembers();
Member master = members.iterator().next();
