大家有遇到这个问题的吗？麻烦可以指点一下，谢谢

HA集群很快将不再被支持，建立因果集群。

@graphway 好的，谢谢

我在同一台机器上部署，出错的原因是端口冲突，但是错误提示却并不明显。 但是你这个在不同的机器上，这个概率比较小，是否别的进程也占用了某个端口。

Caused by: java.util.concurrent.TimeoutException: Conversation-response mapping:
{1/13#=ResponseFuture{conversationId=‘1/13#’, initiatedByMessageType=join, response=null}}

检查一下 网络 端口 防火墙
