我一直在设置一个包含3个节点(A,B,C)的Mesos集群,其中Mesos Master / Slave和ZooKeeper进程在每个Docker容器中运行。
由于使用Ansible执行包含docker run
的群集设置,
除了特定于节点的配置(hostname,zookeeper_myid等)之外,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 。

&#34;目前没有主人领导......&#34;在节点B上
节点C被选为主节点。 访问节点A上的mesos管理页面已成功重定向到节点C.
但它没有将节点B重定向到节点C,显示&#34;没有主人当前正在领导......&#34;代替。
主节点检测到3个从属中只有2个
在主节点(当前节点C)上,检测到3个从站中的2个。 2个检测到的奴隶是;节点A和C
那么,这些问题的可能原因是什么?
