   Bases: :class:`airflow.models.BaseOperator`

   Moves data from Microsoft SQL Server to Hive. The operator runs
   your query against Microsoft SQL Server, stores the file locally
   before loading it into a Hive table. If the ``create`` or
   ``recreate`` arguments are set to ``True``,
   a ``CREATE TABLE`` and ``DROP TABLE`` statements are generated.
   Hive data types are inferred from the cursor's metadata.
   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 table 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``.
