Question

我正在尝试从Spark Standalone群集中将模型学习保存到S3。但我有这个错误：

我在spark-defaults.conf中的extraClassPath中添加了Hadoop-aws aws-sdk

到目前为止我尝试过：我发送了一个由sbt汇编编译的胖jar的spark-submit（我还在sbt中添加了这些依赖项）。我的AWS凭证将在主环境中导出

有什么想法我需要探索解决这个问题吗？

谢谢！

这是一个aws类，因此您需要确保您的CP具有* aws-java JAR所构建的hadoop-aws JAR的确切集合。

mvnrepository列出了这些依赖项。

我有一个项目，其生活的全部目标是解决WTF错误的blobstore连接器绑定，cloudstore。您可以在spark-shell或真实的spark查询中使用它来帮助诊断事物。
