      Description

      Run an attached DAG, for example as:

      airflow test airflow-hive-sample-utf utf-snowman 2017-01-01

      Imporant part:

      unicode_snowman = unichr(0x2603)

      op_test_select = HiveOperator(
      task_id='utf-snowman',
      hql='select \'' + unicode_snowman + '\' as utf_text;',
      dag=dag)

      It should return a single row with an unicode snowman, but instead ends with error:

      UnicodeEncodeError: 'ascii' codec can't encode character u'\u2603' in position 8: ordinal not in range(128)

      The same applies for unicode characters in external .hql files.

      Why is it a problem? Not because of snowmen, but I need to replace some unicode chars in a Hive ETL query.
