------------------------------------------
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 "_".
