> Some tools which upload to S3 and use a object terminated with a "/" as a directory marker,
for instance "s3n://mybucket/mydir/". If asked to iterate that "directory" via listStatus(),
then the current code will return an empty file "", which the InputFormatter happily assigns
to a split, and which later causes a task to fail, and probably the job to fail.
