【问题描述】：
我在做最简单的zookeeper/storm/topology/多节点测试。
一切都很好，但是监督者在最后阶段死了（当风暴监督者试图运行拓扑时）。
我有 3 个虚拟机（ubuntu-16.04.2.）主机。
每个主机都有相同的环境（包括依赖项）：
- zookeeper-3.4.10
- apache-storm-1.1.1
三台主机的名称：
storm-nimbus：这个 id nimbus 主机。
storm-sv-1：这是第一个主管。
storm-sv-2：这是第二个主管。
三台主机的配置部分相同/etc/hosts。
192.168.3.132 zk1.nf.dev st1.nf.dev
192.168.3.130 zk2.nf.dev st2.nf.dev
192.168.3.131 zk3.nf.dev st3.nf.dev
动物园.cfg
...
dataDir=/home/test/1/zookeeper/data/
server.1=zk1.nf.dev:2888:3888
server.2=zk2.nf.dev:2888:3888
server.3=zk3.nf.dev:2888:3888
...
storm.yaml
...
storm.zookeeper.servers:
- "zk2.nf.dev"
- "zk3.nf.dev"
nimbus.seeds: ["st1.nf.dev"]
storm.local.dir: "/home/test/1/storm-local"
...
---测试步骤---
1) 在这三台主机上运行 zookeeper 服务器。 使用 zkCli.sh 测试 zookeeper 状态。 3个zookeeper节点就可以了。
2) 在 nimbus 主机(192.168.3.132)上运行storm ui
3) 在 nimbus 主机(192.168.3.132)上运行storm nimbus
4) 验证 ui 页面中的 nimbus 状态(http://192.168.3.132:8080/)。没关系。
5) 在 nimbus 主机(192.168.3.132) 上提交 wordcount 拓扑
在 ui 页面中验证拓扑状态。没关系。
6) 在 supervisor 主机（192.168.3.130, 192.168.3.131）上运行storm supervisor。
7) 在 ui 页面中验证主管和拓扑状态。
两个主管出现在 UI 页面上。 : 好的
-
在每个主管页面中：
“Slots”和“Avali slot”不为 0。：OK
“Used slots”始终为 0。：这是个问题。
8) 大约 2 分钟后主管死亡

每次测试的时候我都清除了zookeeper数据和风暴临时数据。
如何解决以下错误消息：“无法从种子主机 [st1.nf.dev] 中找到领导者 nimbus。您是否为配置 nimbus.seeds 指定了有效的 nimbus 主机列表？”
Ping 到 'st1.nf.dev' 没问题。为什么主管找不到'st1.nf.dev'？
