我已经从Intellij创建了jar的spark + scala代码，并尝试在dev集群中运行jar，但我最终得到以下错误：

请问您如何排除META-INF详细信息？

感谢。

Answer 1

您需要添加maven-shade插件并使用excludes，如下所示：

 <plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>
           ..
          <filters>
            <filter>
              <artifact>*:*</artifact>
              <excludes>
                <exclude>META-INF/*.SF</exclude>
                <exclude>META-INF/*.DSA</exclude>
                <exclude>META-INF/*.RSA</exclude>
              </excludes>
            </filter>
          </filters>

这将删除已签名的文件并解决您的问题。
