我已经建立了一个由3个节点（a，b，c）组成的mesos集群，mesos主/从和zookeeper进程在每个docker容器中运行。
自群集设置以来，包括 docker run 使用ansible执行，除了节点特定的配置（主机名、zookeeper\u myid等），3个节点之间应该没有区别。
问题是。。。
节点a上的zookeeper警告
zookeeper仅在节点a上显示以下消息。

节点b上的zookeeper显示以下消息。

节点c上的zookeeper显示以下消息。

节点b上的“当前没有主节点在引导…”
节点c被选为主节点。访问节点a上的mesos管理页已成功重定向到节点c。
但它不会将节点b重定向到节点c，而是显示“当前没有主节点在引导…”。
主节点仅检测到3个从属节点中的2个
在主节点（当前为节点c）上，检测到3个从节点中的2个。检测到2个从机；节点a和c
那么，这些问题的可能原因是什么呢？
