无法在Apache Storm群集中使用远程从属节点

Question

我在跟踪http://jayatiatblogs.blogspot.com/2011/11/storm-installation.html尝试在Amazon Web服务上使用带有Ubuntu14.04 LTS的少数虚拟机（EC2）配置Apache Storm远程集群。

我的主节点是10.0.0.230，从节点是10.0.0.79。我的zookeeper位于我的主节点中。当我使用storm-jar-storm-starter-0.9.4-jar-with-dependencies时。罐子Storm。开胃菜。RollingTopWords production topology remote在主节点中，出现以下消息，表明已成功提交：

339  [main] INFO  storm.starter.RollingTopWords - Topology name: production-topology

然而，在Storm UI的集群摘要中，有0个主管、0个已用插槽、0个空闲插槽和0个执行器

下面是我的动物园。我的主节点的cfg：

tickTime=2000
dataDir=/home/ubuntu/zookeeper-data
clientPort=2181

我的主节点的storm.yaml：

 storm.zookeeper.servers:
     - "10.0.0.230"
 storm.zookeeper.port: 2181

 nimbus.host: "localhost"
 nimbus.thrift.port: 6627
 nimbus.task.launch.secs: 240

 supervisor.worker.start.timeout.secs: 240
 supervisor.worker.timeout.secs: 240

 storm.local.dir: "/home/ubuntu/storm/data"   
 java.library.path: "/usr/lib/jvm/java-7-oracle"

暴风雨。我的从属节点的yaml：

 storm.zookeeper.server:
     - "10.0.0.230"
 storm.zookeeper.port: 2181
 nimbus.host: "10.0.0.230"
 nimbus.thrift.port: 6627

 storm.local.dir: "/home/ubuntu/storm/data"
 java.library.path: "/usr/lib/jvm/java-7-oracle"

 supervisor.slots.ports:
     - 6700
     - 6701
     - 6702
     - 6703
     - 6704

我用过zkCli。sh-服务器10.0.0.230:2181要连接到主节点上的zookeeper，它可以正常工作：

我用的是Storm光环

来自主管。来自我的从节点的日志，它显示我的从节点倾向于连接到本地主机上的zookeeper，尽管我在storm中已经指定了。我的从属节点的yaml表示我的动物园管理员在我的主节点中。为什么会发生这种情况，如何解决？

那么，为什么在Storm UI的集群摘要中有0个主管、0个已用插槽、0个空闲插槽和0个执行器呢

当我在Storm UI的拓扑摘要中单击生产拓扑时，有0个Num workers、0个Num executors、0个Num tasks？为什么没有喷口的信息显示

Answer 1

我发现了问题。我应该在我的从节点上设置我的动物园管理员，而不是在我的主节点上。现在问题解决了
