FileStatus[] files = super.listStatus(job);
for (int i = 0; i < files.length; i++) {
FileStatus file = files[i];
if (file.isDirectory()) { // it's a MapFile
Path dataFile = new Path(file.getPath(), MapFile.DATA_FILE_NAME);
FileSystem fs = file.getPath().getFileSystem(job);
// use the data file
files[i] = fs.getFileStatus(dataFile);
}
}
return files;
