Michael Mole commented on AIRFLOW-1153:

>     so the following centence won't work, because 'mynumber' doesn't work for sql sentence.
>     test_hiveoperator = HiveOperator(
>         task_id='hive_test',
>         hiveconf_jinja_translate=True,
>         hql = ''' use myDB;
>             INSERT OVERWRITE TABLE t2
>             select * from t1 where t1.x > ' ${hiveconf:mynumber}'
>         ''',
>         params={'mynumber': 2},
>         dag=dag
