本文介绍了当遇到Hadoop程序因找不到core-site.xml和hdfs-site.xml配置文件而出错时的解决方案。通常需要将这两个文件复制到项目的bin目录下，并确保在IDE中刷新项目以使更改生效。
出现这个错误因为你没有把core-site.xml和hdfs-site.xml放到项目下

程序运行开始就要调用这两个配置文件，这两个文件就是配置Hadoop时候的配置文件，只需要把至两个文件copy到你这个项目的bin目录下，复制过去一定要记住刷新一下eclipse，在项目的空白处右击鼠标，选择Refresh。

或者用图形化界面，找到hadoop配置文件，然后复制这两个文件到你的项目的bin目录下，也要刷新。

Maven下项目使用没有任何问题，但是使用Spring boot 项目就出问题，怀疑是容器问题，查阅了相当多的资料，所有的大部分解决方案都是 拷贝core-site.xml到本地项目中，然后将下列配置添加到core-site.xml配置文件中，然后重新编译项目，然后再进行PostMan访问，发现还是不行，同样报错 第一种，解决方案来源：https://blog.youkuaiyun.com/dufufd/a...

unknown protocol: d我们需要在一个本地磁盘路径前面加上 file:// 来表示 URL 得到一个 file://d:/abc，不能直接 D:/abc 这种写法。 你的错误就在于直接用 d:/abc 当 URL，所以它报告错误说不认识 d 这种协议。String url = "file://" + filePath;unknown protocol: f解决办法：解析的文件名包括路
