使用fileSystem的delete方法無法刪除文件或目錄

Exception in thread "main" java.lang.IllegalArgumentException: Wrong FS: hdfs://h1:9000/out, expected: file:///

at org.apache.hadoop.fs.FileSystem.checkPath(FileSystem.java:381)

at org.apache.hadoop.fs.RawLocalFileSystem.pathToFile(RawLocalFileSystem.java:55)

at org.apache.hadoop.fs.RawLocalFileSystem.getFileStatus(RawLocalFileSystem.java:393)

at org.apache.hadoop.fs.ChecksumFileSystem.delete(ChecksumFileSystem.java:452)

at mapreduce.WordCountApp.main(WordCountApp.java:36)

由於獲取fileSystem對象的時候沒有傳入訪問地址導致。

FileSystem fileSystem = FileSystem.get(new URI(INPUT_PATH),conf);
