这三台主机具有/ etc / hosts的相同配置部分。
203.xx.xx.253 server0
203.xx.xx.254 server1
203.xx.xx.255 server2
dataDir=/home/xxx/zookeeper/data/`
server.0=server0:2888:3888
server.1=server1:2888:3888
server.2=server2:2888:3888
storm.zookeeper.servers:
- "server0"
- "server1"
- "server2"
nimbus.seeds: ["server0"]
storm.local.dir: "/home/xxx/storm/data"
在这三台主机上运行zookeeper服务器。测试动物园管理员状态。没关系。
在主机（服务器0）上运行storm nimbus。在主机（服务器0）上运行storm ui
在主机（server0，server1，server2）上运行风暴管理器
在ui页面中验证风暴状态。没关系。
提交拓扑，成功
在1分钟左右的主管死亡后，有一个主管还活着（server0）。

如何解决以下错误消息：“从种子主机server0中找不到领导者nimbus。您是否为config nimbus.seeds指定了nimbus主机的有效列表？”
Ping到“ server0”是可以的。为什么主管无法找到“ server0”。
谢谢
