Apache-storm主管在多节点环境中尝试运行拓扑时死亡。

Question

我在做最简单的动物园管理员/风暴/拓扑/多节点测试。

一切都很好，但是主管在最后一个阶段死亡(当风暴主管试图运行拓扑时)。

我有3个VM(ubuntu16.04.2)主机。

每个主机具有相同的环境(包括依赖关系)：

-动物园管理员-3.4.10

阿帕奇-风暴-1.1.1

三个主机的名称：

风暴-尼布斯:这个身份敏捷的主机。

风暴-sv-1:这是第一个主管。

风暴-sv-2:我是第二主管。

这三台主机具有/etc/host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动物园管理员服务器。使用zkCli.sh测试动物园管理员状态。3个饲养员节点良好。

2)在nimbus主机上运行风暴ui (192.168.3.132)

3)在nimbus主机上运行风暴nimbus (192.168.3.132)

4)验证ui页面(http://192.168.3.132:8080/)中的nimbus状态。这很好。

5)在nimbus主机上提交字计数拓扑(192.168.3.132)

验证ui页面中的拓扑状态。没关系。

6)在主管主机上运行风暴监控器(192.168.3.130,192.168.3.131)。

7)验证ui页面中的管理器和拓扑状态。

• 两个主管出现在UI页面上。：：好
• 在每个主管页面中：

- "Slots" and "Avali slots" are not 0. : OK
- "Used slots" is always 0. : This is problem.

​

8)阿庞特2分钟后，主管死亡

每一次测试时间，我都要清理动物园管理员的数据和风暴临时数据。

如何解决以下错误信息：“无法从种子主机st1.nf.dev中找到主nimbus。您是否为nimbus.seeds配置指定了一个有效的nimbus主机列表？”

平到'st1.nf.dev‘是可以的。为什么主管找不到'st1.nf.dev'？

Answer 1

1. 停止风暴
2. 使用命令行连接到动物园管理员 ..path到动物园管理员bin/zkCli.sh rmr /storm退出
3. 重新启动风暴
