我是内存数据网格和Hazelcast的新手。我正在尝试在官方网站上的演示应用程序。
https://training.hazelcast.com/demo-getting-started-with-hazelcast-imdg/277088/scorm/f2u8hre5zf9p
它提到多次运行应用程序时，应将成员添加到同一群集中。
但是，第二次运行该程序时，似乎新成员未添加到同一群集中。
想知道我的设置是否有任何问题，谢谢。
环境：Eclipse IDEJDK 13hazelcast 3.12.2

您也许在本地环境中安装了虚拟化软件？ hazelcast的默认多播地址可能会发生冲突。尝试将地址更改为：224.0.0.1：
cfg.getNetworkConfig（）。getJoin（）。getMulticastConfig（）。setMulticastGroup（“ 224.0.0.1”）;
