解決：
1.添加jar包：
https://github.com/downloads/congainc/patch-hadoop_7682-1.0.x-win/patch-hadoop_7682-1.0.x-win.jar
2.在windows項目中core-site.xml添加配置文件
<property> <name>fs.file.impl</name> <value>com.conga.services.hadoop.patch.HADOOP_7682.WinLocalFileSystem</value> <description>Enables patch for issue HADOOP-7682 on Windows</description>
