        Loads a local file into Hive
        Note that the table generated in Hive uses ``STORED AS textfile``
        which isn't the most efficient serialization format. If a
        large amount of data is loaded and/or if the tables gets
        queried considerably, you may want to use this operator only to
        stage the data into a temporary table before loading it into its
        final destination using a ``HiveOperator``.
