Question

我正在进行最简单的zookeeper / storm / topology / muti-node测试。

一切都很好，但主管在最后阶段（当风暴管理员试图运行拓扑时）死亡。

我有3个VM（ubuntu-16.04.2。）主机。

每个主机具有相同的环境（包括依赖项）：

- zookeeper-3.4.10

- apache-storm-1.1.1

三个主机的名称：

storm-nimbus：这个id nimbus主机。

storm-sv-1：这是第一位主管。

storm-sv-2：这是第二位主管。

这三台主机具有/ etc / hosts的相同配置部分。

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

zoo.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节点都没问题。

2）在nimbus主机上运行storm ui（192.168.3.132）

3）在nimbus主机上运行storm nimbus（192.168.3.132）

4）在ui页面（http://192.168.3.132:8080/）中验证nimbus状态。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）在主管主持人身上运行风暴监督员（192.168.3.130,192.168.3.131）。

7）在ui页面中验证管理程序和拓扑状态。

UI页面上显示两个主管。：好的
在每个主管页面中：
- “Slots”和“Avali slots”不是0.：OK
- “使用的插槽”始终为0.：这是问题。

8）经过2分钟后，主管去世了

每次测试时我都清除了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]找到领导者nimbus。您是否为config 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'？

Answer 1

停止风暴

使用命令行

连接到zookeeper

..path to zookeeper bin/zkCli.sh 
rmr /storm 
quit

重启风暴
