反熵协议是一种八卦协议.http://en.wikipedia.org/wiki/Gossip_protocol.我想知道是否有人可以在这里解释字熵的重要性.

如何配置Hazelcast（最适合当前使用的版本：3.1.2），以在一台计算机上运行2个hazelcast实例，并在启动过程中阻止第一个实例，直到两个实例都存在？

hazelcast.initial.min.cluster.size

可以通过hazelcast.initial.min.cluster.size在不同计算机上运行两个实例时实现上述阻止行为：

Config cfg = new Config(); 
cfg.setProperty("hazelcast.initial.min.cluster.size",
  Integer.toString(minimumInitialMembersInHazelCluster));
cfg.getGroupConfig().setName(clusterName);
hazelInst = Hazelcast.newHazelcastInstance(cfg);

在不同的机器上运行，我得到输出
