Fixing java.lang.NoSuchMethodError: com.amazonaws.util.StringUtils.trim
Fixing java.lang.NoSuchMethodError: com.amazonaws.util.StringUtils.trim

}
public void map(Object key, Text value, Context context

}
这一行：System.out.println(StringUtils.trim("hi")); 导致 java.lang.NoSuchMethodError: com.amazonaws.util.StringUtils.trim 当我在 Qubole 中 运行 它但在本地机器上工作正常时。
这是我的 POM 导入：
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk-s3</artifactId>
<version>1.11.365</version>
</dependency>
<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-java-sdk-core</artifactId>
<version>1.11.365</version>
</dependency>
使用 Uber JAR 插件：
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-shade-plugin</artifactId>
<version>3.1.1</version>
<configuration>
<!-- put your configurations here -->

为什么 Hadoop 找不到 com.amazonaws.util.StringUtils.trim 即使我在文件中导入它，在 POM 中导入它，并将所有依赖项导出到一个胖 JAR 中？
我需要导入什么才能使用 com.amazonaws.util.StringUtils.trim？
这是我的依赖项

很可能是由于 class 中的本地和远程差异。也许您提供的 JAR 已经出现在 class 路径中的不同版本中，并且首先加载。查看 this answer 了解如何在远程上找到包含 class 文件的 JAR。
Class klass = StringUtils.class;
URL location = klass.getResource('/' + klass.getName().replace('.', '/') + ".class");
希望location里面有JAR版本号，这样你就可以根据本地确认远程版本。
由于您已经在着色，您可以通过重新打包依赖项、将第三方 class 重新定位到您自己的 com.myorg 包中来解决这个问题，例如com.amazonaws.util.StringUtils 变为 com.myorg.com.amazonaws.util.StringUtils。参见 Using Package Relocation in the maven-shade-plugin。如果有很多或很大的依赖关系，我不会这样做，但这取决于你。
我在 运行 spark-submit 时遇到这样的错误。我意识到代码是使用带有 hadoop 3.2 库的 spark 3.0.0 构建的，我的本地 spark 版本是 2.4.7。我使用 hadoop 3.2 升级到 Spark 3 并将 aws-java-sdk-1.11.828.jar（这是我的代码使用的 sdk）复制到 spark jars 目录并且它有效！

我在 运行 spark-submit 时遇到这样的错误。我意识到代码是使用带有 hadoop 3.2 库的 spark 3.0.0 构建的，我的本地 spark 版本是 2.4.7。我使用 hadoop 3.2 升级到 Spark 3 并将 aws-java-sdk-1.11.828.jar（这是我的代码使用的 sdk）复制到 spark jars 目录并且它有效！
