从Hazelcast网格获取主IP地址 [英] Get the Master Ip Address from Hazelcast grid

问题描述

我想从实例HazelcastInsatnce的HazelcastInsatnceImpl的Hazelcast节点上使用masterIpAddress。

I would like to get the masterIpAddress use on the Hazelcast node in HazelcastInsatnceImpl from an instance HazelcastInsatnce.

有人知道该怎么做吗？

感谢您的帮助

推荐答案

Hazelcast集群中没有真正的大师。最古老的节点扮演着特殊的角色，因此您可以将其想象为主节点。

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".

要获取此节点，请从成员列表中检索第一个元素。

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();
