------------------------------------------

             Summary: MapFileOutputFormat#getReaders bug with invisible files/folders
                 Key: MAPREDUCE-5448
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5448
             Project: Hadoop Map/Reduce
          Issue Type: Bug
            Reporter: Maysam Yabandeh
            Assignee: Maysam Yabandeh
            Priority: Minor


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 "_".
