由于错误指示未找到 class backtype.storm.messaging.netty.Context。
Caused by: java.lang.ClassNotFoundException: backtype.storm.messaging.netty.Context
在 Storm 1.0.0 中，这是一个重命名许多包的重大重构。我想你现在想使用 org.apache.storm.messaging.netty.Context。
storm.messaging.transport: "org.apache.storm.messaging.netty.Context"
问题是我的 JAVA_HOME env var 指向了错误的文件夹。
之前：
JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.101-1.b14.fc24.x86_64/jre/
在之后：
JAVA_HOME=/usr/lib/jvm/java-1.8.0-oracle-1.8.0.92.x86_64/

一旦我将 JAVA_HOME 切换到 /usr/lib/jvm/java-1.8.0-oracle-1.8.0.92.x86_64/ 我就能够编译示例 tolology 并将其提交到远程集群（仍然是本地安装的 storm 并且 zookeeper/nimbus/supervisor/ui/logviewer 在本地 运行）
还要记住，有一篇 Yahoo 文章，他们在其中推荐 '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

由于错误指示未找到 class backtype.storm.messaging.netty.Context。
Caused by: java.lang.ClassNotFoundException: backtype.storm.messaging.netty.Context
在 Storm 1.0.0 中，这是一个重命名许多包的重大重构。我想你现在想使用 org.apache.storm.messaging.netty.Context。
storm.messaging.transport: "org.apache.storm.messaging.netty.Context"
问题是我的 JAVA_HOME env var 指向了错误的文件夹。
之前：
JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk-1.8.0.101-1.b14.fc24.x86_64/jre/
在之后：
JAVA_HOME=/usr/lib/jvm/java-1.8.0-oracle-1.8.0.92.x86_64/
我得到了检查风暴是否正确安装的建议，通过风暴示例中的 运行 示例 java 拓扑。
我关注了这位官方tutorial。
cd ~/Development/storm/examples/storm-starter
mvn package

一旦我将 JAVA_HOME 切换到 /usr/lib/jvm/java-1.8.0-oracle-1.8.0.92.x86_64/ 我就能够编译示例 tolology 并将其提交到远程集群（仍然是本地安装的 storm 并且 zookeeper/nimbus/supervisor/ui/logviewer 在本地 运行）
还要记住，有一篇 Yahoo 文章，他们在其中推荐 '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 可以 对您的系统产生负面影响，因为 storm 1.0+ 的 类 结构发生了变化。
类 在 1.0.1 中从 backtype.storm.
重新打包到 org.apache.storm
