Question

当我在本地代码中运行我的代码时，它工作正常。但是，当我在集群中运行它时，似乎在我的Jar文件中遗漏了一些依赖项：

18/05/23 10:46:02 ERROR ApplicationMaster: User class threw exception: java.lang.NoSuchMethodError: org.apache.http.conn.ssl.SSLConnectionSocketFactory.<init>(Ljavax/net/ssl/SSLContext;Ljavax/net/ssl/HostnameVerifier;)V

        at com.amazonaws.http.apache.client.impl.ApacheConnectionManagerFactory.create(ApacheConnectionManagerFactory.java:58)

这是SBT文件：

我的罐子有什么问题？在IntelliJ IDEA中，我选择了班级检查选项并粘贴了SSLConnectionSocketFactory。找到该类并引用httpclient-4.3.6.jar

Spark附带了许多库，您可能与其中一个库发生冲突。

我认为我的io.netty.netty-all包有类似的问题。我们最终将服务器上的该软件包升级到稍微更新的次要版本，但这是因为我们正在构建部署在节点上的spark集成。

您可以尝试使用这些参数部署spark应用

--conf 'spark.driver.extraJavaOptions=-verbose:class'
--conf 'spark.executor.extraJavaOptions=-verbose:class'

那些允许你看到类路径。我很确定你会在那里看到相互冲突的包裹。我开始检查加载了什么版本的netty，因为我非常确定它取决于httpclient。

Spark异常：java.lang.NoSuchMethodError：org.apache.http.conn.ssl.SSLConnectionSocketFactory
