使用Apache Storm 1.0.0在生产集群中运行拓扑时出错，拓扑无法启动

Question

>

灵光升起

StormUI启动

我使用的两个工人都起来了

Zookeper已启动

我和暴风一起跑

Storm罐myjar.jar MyClass

Nimbus提交拓扑

该拓扑的日志文件不会出现在workers中。

我在supervisor.log上的worker中有以下日志：

所以我确信我与nimbus有连接问题，但是worker中的属性文件是：

 storm.zookeeper.servers:
     - "192.168.22.209"
     - "192.168.22.216"
     - "192.168.22.217"

 storm.local.dir: "/app/home/storm"


 storm.zookeeper.root: "/storm-prod"

# 
 nimbus.seeds: ["192.168.120.96"]

错误在哪里，我如何修复它？

谢了！

Answer 1

在这个上下文中发生的情况是，Storm supervisor第一次从Storm.yaml seeds/host中配置的任何内容解析nimbus，然后使用nimbus主机名下载拓扑构件。

如果这是正确的，那么DNS对于群集设置是必需的。这远远不够理想，特别是在像Kubernetes这样的编排环境中使用容器时。

我目前使用的解决方案是添加

storm.local.hostname: "<local.ip.value>"
