>
> PrestoValueCheckOperator and PrestoIntervalCheckOperator don't forward
> user-supplied args as keyword args to their parent class initializers, which
> causes an exception to be raised by the apply_defaults decorator (see
> https://github.com/apache/incubator-airflow/blob/cf6d50c0e3d59ec9155be445c127c90a05cc90a2/airflow/utils/decorators.py#L46).
> For example:
> >>> from airflow.operators import PrestoIntervalCheckOperator
> >>> p = PrestoIntervalCheckOperator(task_id='id', table='table',
> >>> metrics_thresholds=0)
> Traceback (most recent call last):
> File "<stdin>", line 1, in <module>
> File "/.venv/lib/python3.5/site-packages/airflow/utils/decorators.py", line
> 86, in wrapper
> result = func(*args, **kwargs)
> File
> "/.venv/lib/python3.5/site-packages/airflow/operators/presto_check_operator.py",
> line 99, in __init__
> *args, **kwargs)
> File "/.venv/lib/python3.5/site-packages/airflow/utils/decorators.py", line
