我正在尝试在Hazelcast 3.8.8中建立分区组。我的主要目标是将驻留在2台物理计算机中的4个群集成员分为2个分区组。当我启用分区组时，似乎没有用，组也没有建立。您能告诉我启用分区组时缺少什么吗？
我已经尝试通过hazelcast.xml启用分区分组。用group-type =“ CUSTOM”测试，并将驻留在本地和我们服务器中的成员分成两个不同的member-group。成员组成一个集群，但似乎未建立分区组。我看不到与此有关的任何错误消息，但日志中也没有确认消息。最后，我启用了[[“ HOST_AWARE”，并以相同的网络接口在本地启动了2个成员，并检查了管理中心。我所看到的是成员的行为类似于“ PER_MEMBER”，因为它处于默认配置中，并且继续将其备份彼此迁移。在这种情况下，我期望没有备份，因为两者都会组成分区组。

partition-group时，分区机制回退到特殊的partition-group类型，并将现有成员分为两个分区组。这是为了确保每个分区至少有一个备份。否则，将不会进行任何备份，丢失成员将导致立即丢失数据。参见代码库：BackupSafeMemberGroupFactory
PS：您配置group-type="CUSTOM"时，我不明白出了什么问题。
