   .. note:

       Following fields are template-supported : ``query``, ``script_location``,
       ``sub_command``, ``script``, ``files``, ``archives``, ``program``, ``cmdline``,
       ``sql``, ``where_clause``, ``extract_query``, ``boundary_query``, ``macros``,
       ``tags``, ``name``, ``parameters``, ``dbtap_id``, ``hive_table``, ``db_table``,
       ``split_column``, ``note_id``, ``db_update_keys``, ``export_dir``,
       ``partition_spec``, ``qubole_conn_id``, ``arguments``, ``user_program_arguments``.
       You can also use ``.txt`` files for template driven use cases.

   .. note:

       In QuboleOperator there is a default handler for task failures and retries,
       which generally kills the command running at QDS for the corresponding task
       instance. You can override this behavior by providing your own failure and retry
       handler in task definition.
