Mesos + ZooKeeper不能正常工作

我一直在build立一个由3个节点（A，B，C）组成的Mesos集群，在每个Docker容器中运行Mesos Master / Slave和ZooKeeper进程。

由于使用Ansible执行包括docker docker run集群设置，因此除了节点特定的configuration（主机名，zookeeper_myid等）之外，3个节点之间应该没有区别。

问题是…

Zookeeper节点A上的警告

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。

 2015-05-25 03:12:31,183 [myid:] - INFO [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:NIOServerCnxnFactory@197] - Accepted socket connection from /<ip-nodeA>:56496 2015-05-25 03:12:31,184 [myid:] - WARN [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:ZooKeeperServer@822] - Connection request from old client /<ip-nodeA>:56496; will be dropped if server is in ro mode 2015-05-25 03:12:31,184 [myid:] - INFO [NIOServerCxn.Factory:0.0.0.0/0.0.0.0:2181:ZooKeeperServer@868] - Client attempting to establish new session at /<ip-nodeA>:56496 2015-05-25 03:12:31,191 [myid:] - INFO [SyncThread:0:ZooKeeperServer@617] - Established session 0x14d89037ccd0002 with negotiated timeout 10000 for client /<ip-nodeA>:56496 

节点B上“没有主人正在领导…”

节点C被选为主节点。 访问节点A上的mesospipe理页面已成功redirect到节点C.

但是它并没有将节点Bredirect到节点C，而是显示“No master is leading leading …”。

主节点只能检测到3个从站中的2个

在主节点（当前节点C）上，检测到3个从节点中的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？
