Patrick McKenna created AIRFLOW-814:
---------------------------------------
Summary: Presto*CheckOperator should use keyword args during
initialization
Key: AIRFLOW-814
URL: https://issues.apache.org/jira/browse/AIRFLOW-814
Project: Apache Airflow
Issue Type: Bug
Reporter: Patrick McKenna
Priority: Trivial
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)
