我是java和Storm的新手所以请原谅任何明显的错误。 我正试图用水槽连接器进行暴风雨 但它崩溃了以下错误：

你能解释一下我错过了什么吗？

5 个答案:

答案 0 :(得分：6)

似乎关键在于：

Caused by: java.lang.ClassNotFoundException: org.apache.zookeeper.server.NIOServerCnxn$Factory

这似乎是由使用3.4.5的版本zookeeper引起的。您是否尝试过降级，可能是版本3.3.6？

分支-3.3包含内部类NIOServerCnxn$Factory但分支-3.4包含NIOServerCnxnFactory而不是

答案 1 :(得分：1)

似乎最后的jar丢失了zookeeper。尝试添加：

   <dependency>

        <version>${flume.version}</version>

如果没有帮助问题：

答案 3 :(得分：0)

我也面临同样的问题，我在案例中注意到的问题是： 我使用storm-9.0.1和Zookeeper 3.4.5。

通过将我的zookeeper更改为3.3.6或将风暴更改为9.0.2，我的问题已经解决了。

所以Storm-9.0.1与Zookeeper 3.3.6兼容，Storm 9.0.2与Zookeeper 3.4.5兼容

答案 4 :(得分：-1)

经过几天的敲击，我决定改变方法，显然Eclipse可以运行项目，因为它没有任何问题。

从eclipse创建一个uberjar并将所有引用的jar放在项目的lib文件夹中，然后使用java -jar在服务器中运行uberjar解决了这个问题。

不是一个好的解决方案而且我从未理解为什么maven无法运行该项目但它有效。
