服务器mk-worker的初始化时出错

Question

我试图使用maven在本地模式下使用storm-0.8.1和zookeeper-3.3.3来执行wordcount示例。但是，每次我运行此命令我收到以下错误：

mvn exec:java -Dexec.mainClass="com.test.newpackage.TopologyMain" Dexec.args="resource/words.txt“

我搜查，发现前面我使用饲养员3.4.5所以，后来我改变了我的饲养员到3.3.3，但仍。不能执行。如果有人想引用我的代码这里是link

根据this discussion了类似的问题被重新排序的依赖性解决。因此，我建议你在上面移动的动物园管理员dependency元素你的依赖列表。

编辑：

我怀疑你的问题来自于一个classpath顺序问题。即存在于多个伪影中的相同类别，并且当前加载的违规类别的版本是错误的。

要解决此问题，您需要重新排序您的类路径（您可能知道，当同一个类在classpath中多次出现时：第一个win）。要重新排列你的classpath，你需要改变你的pom.xml声明的顺序（因为行家2.0.9至少）从maven site

报价：

since Maven 2.0.9 it's the order in the declaration that counts: the first declaration wins.
