Title: Ignore system files when using FileInputFormat

The FileInputFormat adds also files that start with an underscore ( _ ) when the given input file is a directory.
MapReduce Jobs create an empty `_SUCCESS` file and a `_logs` directory. These are usually not wanted.

This error also caused empty InputSplits.
