hazelcast - 未建立分区组

问题描述

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 个物理机中的 4 个集群成员分组为 2 个分区组。当我启用分区组时，它似乎没有工作并且组没有建立。你能告诉我启用分区组我缺少什么吗？

我试图通过 hazelcast.xml 启用分区分组。使用group-type="CUSTOM" 进行测试，并将驻留在我本地和我们服务器中的成员分成两个不同的 member-group。成员形成了一个集群，但似乎没有建立分区组。我看不到任何有关此的错误消息，但日志中也没有确认消息。最后，我启用了“HOST_AWARE”并在本地使用相同的网络接口启动了 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”，因为它在默认配置中并继续相互迁移他们的备份。

解决方案

当只有一个partition-group时，分区机制回退到一个特殊的partition-group类型，并将现有的成员分成两个 partition group。这是为了确保每个分区至少有一个备份。否则将不会有任何备份，并且成员的丢失将导致立即数据丢失。参见代码库：BackupSafeMemberGroupFactory

更新：关于分区组是否启用...

不幸的是，除了管理中心之外，没有日志或公共 API 来显示分区组是否正在使用中。但是您期望这些信息将打印在日志中是正确的。你可以在 Hazelcast Github repo 提交问题。
