Wrong FS: hdfs://xxx/xxx expected: file:///

Eclipse调用HDFS API上传文件时出现了如下错误：

Exception in thread "main" java.lang.IllegalArgumentException: Wrong FS: hdfs://master:9000/user/Administrator, expected: file:///at org.apache.hadoop.fs.FileSystem.checkPath(FileSystem.java:659)at org.apache.hadoop.fs.RawLocalFileSystem.pathToFile(RawLocalFileSystem.java:82)at org.apache.hadoop.fs.RawLocalFileSystem.deprecatedGetFileStatus(RawLocalFileSystem.java:585)at org.apache.hadoop.fs.RawLocalFileSystem.getFileLinkStatusInternal(RawLocalFileSystem.java:803)at org.apache.hadoop.fs.RawLocalFileSystem.getFileStatus(RawLocalFileSystem.java:580)at org.apache.hadoop.fs.FilterFileSystem.getFileStatus(FilterFileSystem.java:425)at org.apache.hadoop.fs.FileSystem.exists(FileSystem.java:1414)at org.apache.hadoop.fs.FileUtil.checkDest(FileUtil.java:499)at org.apache.hadoop.fs.FileUtil.copy(FileUtil.java:351)at org.apache.hadoop.fs.FileUtil.copy(FileUtil.java:341)at org.apache.hadoop.fs.FileUtil.copy(FileUtil.java:292)at org.apache.hadoop.fs.LocalFileSystem.copyFromLocalFile(LocalFileSystem.java:82)at org.apache.hadoop.fs.FileSystem.copyFromLocalFile(FileSystem.java:1884)at com.hellohadoop.FileOperator.Upload(FileOperator.java:48)at com.hellohadoop.FileOperator.main(FileOperator.java:23)

解决的办法是把Hadoop集群的hdfs-site.xml和core-site.xml两个配置文件复制到项目的bin目录下面，就可以正常运行了。
