> MapReduce jobs also produce some invisible files such as _SUCCESS, even when the output
format is MapFileOutputFormat. MapFileOutputFormat#getReaders however reads the entire content
of the job output, assming that they are MapFiles.
> {code}
> Path[] names = FileUtil.stat2Paths(fs.listStatus(dir));
> {code}
> It should use a filter to skip the files that start with "." or "_".
