这是一个如何配置它的示例。
Maven 设置：
笔记：
- （可选）从 spring-data-hadoop 中排除 hadoop-streaming 和 hadoop-tools
- 使用通用版本添加 hadoop-common 和 hadoop-hdfs：2.0.0-cdhX.XX
- 使用 mr1 版本添加 hadoop-tools 和 hadoop-streaming：2.0.0-mr1-cdhX.XX
- Spring Data Hadoop 目前仅支持 MR1。所以请确保您没有将 MR2 包含在其他依赖项中。检查这个
mvn dependency:tree！

弹簧设置（applicationContext.xml）：
替换为fs.default.name您的名称节点域

有了这个，您应该能够访问您的集群。
