Apache-storm Supervisor尝试在多节点环境中运行拓扑时死亡

Question

三个主机的名称：

Storm-光轮：这个id光轮主机。

Storm-SV-1:这是第一主管。

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

...
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.zookeeper.servers:
     - "zk2.nf.dev"
     - "zk3.nf.dev"

nimbus.seeds: ["st1.nf.dev"]

storm.local.dir: "/home/test/1/storm-local"
...

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。

两个主管出现在UI页面上。：好的

在每个主管页面中：

“插槽”和“Avali插槽”不为0。：好的

停止Storm

使用命令行连接到zookeeper

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

重启Storm
