我在 Java Spark 应用程序中遇到 Spark、Hadoop 和 AWS Hadoop 依赖项的兼容性问题。
我本机运行的Spark版本是3.1.2。
问题: 我正在开发一个与 Amazon S3 中存储的数据交互的 Spark 应用程序(版本 3.1.2)。该应用程序使用 Hadoop(版本 3.2.1)并包含 AWS Hadoop 的依赖项。

问题:
运行 Spark 应用程序时,我遇到以下与 IOStatisticsSource 相关的运行时错误:
java.lang.NoClassDefFoundError: org/apache/hadoop/fs/statistics/IOStatisticsSource
问题:
哪些版本的 Hadoop 和 AWS Hadoop 依赖项与 Spark 3.1.2 兼容? 我的依赖项中的 Hadoop 版本之间是否存在冲突? 如果我不使用 S3,是否应该删除 hadoop-aws 依赖项? 我尝试过更新依赖项、删除 hadoop-aws 并配置序列化,但问题仍然存在。
任何有关解决此问题的指导或对这些依赖项兼容性的见解将不胜感激。
