我正在编写一种自动重新平衡群集范围的单例管理器，它使用hazelcast的MembershipListener来跟踪上/下事件：
hazelcastInstance.getCluster().addMembershipListener(new MembershipListener() {
@Override
public void memberAdded(MembershipEvent membershipEvent) {
log.info("{}: got memberAdded event {} ", thisInstance, membershipEvent);
rebalanceLiveNodes(membershipEvent.getMembers());
}
@Override
public void memberRemoved(MembershipEvent membershipEvent) {
log.info("{}: got memberRemoved event {} ", thisInstance, membershipEvent);
rebalanceDeadNodes(membershipEvent.getMembers());
}
@Override
public void memberAttributeChanged(MemberAttributeEvent memberAttributeEvent) {
}
});
然而，看起来如果节点重新启动足够快，它就不会触发＆＃34;删除＆＃34;事件，但只是＆＃34;添加＆＃34;：

我们使用Hazelcast 3.2。 不接受＆＃34;删除＆＃34;是否正常节点重启的事件？..
