Java Apache Storm-初始化时出错（工作）

风暴-1.0.1

我的风暴。yaml：

storm.zookeper.servers:
  - "zookeper"

storm.zookeeper.port: 2181
# nimbus.host: "nimbus"
nimbus.seeds: ["nimbus"]
storm.local.dir: "/var/log/storm"
supervisor.slots.ports:
  - 6700
  - 6701
  - 6702
  - 6703
worker.childopts: "-Xmx768m"
nimbus.childopts: "-Xmx512m"
supervisor.childopts: "-Xmx256m"

storm.messaging.transport: "backtype.storm.messaging.netty.Context"
storm.messaging.netty.server_worker_threads: 1

storm.messaging.netty.max_retries: 100
storm.messaging.netty.max_wait_ms: 1000
storm.messaging.netty.min_wait_ms: 100

在我的主管日志中，我看到：

工作日志包含以下错误：

---

因为错误表明未找到类

backtype.storm.messaging.netty.Context

原因：java.lang.ClassNotFoundException:backtype.storm.messaging.netty.Context

在Storm

1.0.0

中，对许多包进行了重大的重构重命名。我想您现在应该使用

org.apache.storm.messaging.netty.Context

storm.messaging.transport: "org.apache.storm.messaging.netty.Context"

---

请参见

问题在于我的JAVA_HOME env var指向错误的文件夹

之前：

JAVA_HOME=/usr/lib/jvm/JAVA-1.8.0-openjdk-1.8.0.101-1.b14.fc24.x86_64/jre/

之后：

storm.zookeper.servers:
  - "zookeper"

storm.zookeeper.port: 2181
# nimbus.host: "nimbus"
nimbus.seeds: ["nimbus"]
storm.local.dir: "/var/log/storm"
supervisor.slots.ports:
  - 6700
  - 6701
  - 6702
  - 6703
worker.childopts: "-Xmx768m"
nimbus.childopts: "-Xmx512m"
supervisor.childopts: "-Xmx256m"

storm.messaging.transport: "backtype.storm.messaging.netty.Context"
storm.messaging.netty.server_worker_threads: 1
storm.messaging.netty.client_worker_threads: 1
storm.messaging.netty.buffer_size: 5242880
storm.messaging.netty.max_retries: 100
storm.messaging.netty.max_wait_ms: 1000
storm.messaging.netty.min_wait_ms: 100

JAVA_HOME=/usr/lib/jvm/JAVA-1.8.0-oracle-1.8.0.92.x86_64/

我得到了检查storm是否正确安装的建议，方法是运行storm示例中提供的示例java拓扑

我跟着这位官员

给我这个：

当我将JAVA_HOME切换到/usr/lib/jvm/JAVA-1.8.0-oracle-1.8.0.92.x86_64/时，我就能够编译样本Tology并将其提交到远程集群（该集群仍然是storm的本地安装，zookeeper/nimbus/supervisor/ui/logviewer正在本地运行）

还请记住，雅虎的一篇文章建议将“netty”作为传输，并提供以下值：

#storm.messaging.transport: "backtype.storm.messaging.netty.Context"
#storm.messaging.netty.server_worker_threads: 1
#storm.messaging.netty.client_worker_threads: 1
#storm.messaging.netty.buffer_size: 5242880
#storm.messaging.netty.max_retries: 100
#storm.messaging.netty.max_wait_ms: 1000
#storm.messaging.netty.min_wait_ms: 100

这会对你的系统产生负面影响，因为storm 1.0+改变了他们的课程结构

类在1.0.1中从backtype.storm重新打包到org.apache.storm。
