尝试从Java中的HDFS读取文件时出现“错误的FS…预期：file：///”

试试这个：

Configuration configuration = new Configuration();FileSystem fs = FileSystem.get(new URI(<url:port>), configuration);Path filePath = new Path(<path/to/file>);FSDataInputStream fsDataInputStream = fs.open(filePath);BufferedReader br = new BufferedReader(new InputStreamReader(fsDataInputStream));

请参考http://techidiocy.com/java-lang-illegalargumentexception-wrong-fs-
expected-file/

解决了类似的问题。
