scala - 如何在 Spark 提交中将 s3a 与 Apache spark 2.2(hadoop 2.8) 一起使用？

Question

我正在尝试使用使用 hadoop 2.8 版本构建的 spark 2.2.0 从 spark 访问 S3 数据，我正在使用 /jars/hadoop-aws-2.8.3。 jar, /jars/aws-java-sdk-s3-1.10.6.jar 和 /jars/aws-java-sdk-core-1.10.6.jar 在 类路径

我得到以下异常

然后我将 hadoop-common jar 添加到 spark 安装目录 /sparkinstallation/jars/hadoop-common-2.8.3.jar 的 classpath 中，现在我明白了以下错误:

如果我遗漏了什么，有人可以帮忙吗？

我已经提到了链接 - How to use s3 with Apache spark 2.2 in the Spark shell , 但没有帮助

Answer 1

我建议将依赖项添加到您的 spark-submit 命令，如下所示，这将下载所需的所有依赖项。如果你只是添加一个 jar，你可能还缺少一些其他的依赖:

 spark-shell --packages "org.apache.hadoop:hadoop-aws:2.7.3"
 spark-submit --packages "org.apache.hadoop:hadoop-aws:2.7.3"

另一种方法是将依赖项捆绑到您的作业 jar 文件中，然后使用普通的 spark-sbumit
