Are you talking about reading arbitrary files from HDFS?
You can just get a regular InputStream to a Path:
JobConf conf = new JobConf(SomeJob.class);
FileSystem hdfs = FileSystem.get(conf);
FSDataInputStream inputStream = hdfs.open(new Path("/my/path"));
BufferedReader reader = new BufferedReader(new
InputStreamReader(inputStream));
String s = reader.readLine();
