欢欢喜喜写完mapreduce，点开运行报错：Class org.apache.hadoop.hdfs.DistributedFileSystem not found 百度百来百去都没找到问题所在，后来查看了下pom.xml 发现 org.apache.hadoop hadoop-hdfs-client 3.1.3 provided 网上查了下maven中provided的作用，发现：provided不会把jar包打进去破案了去掉这个该死的 provided 重新导入下依赖完美解决问题参考链接：https://blog.csdn.net/u012501054/article/details/80360906
