Subject [jira] [Created] (AIRFLOW-1162) execution_date doesn't have a default value exception
Date Sun, 30 Apr 2017 08:20:04 GMT
Neer Shay created AIRFLOW-1162:
----------------------------------

             Summary: execution_date doesn't have a default value exception
                 Key: AIRFLOW-1162
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-1162
             Project: Apache Airflow
          Issue Type: Bug
          Components: DagRun
    Affects Versions: Airflow 1.8, 1.8.0
         Environment: mysql db, standard linux environment
            Reporter: Neer Shay


Example DAG:
default_args = {
    'owner': 'airflow',
    'depends_on_past': False,
    'start_date': datetime(2017, 4, 27),
    'email': ['airflow@airflow.com'],
    'email_on_failure': False,
    'email_on_retry': False,
}

dag = DAG('tutorial_new_dag', default_args=default_args)

t1 = BashOperator(
    task_id='print_date',
    bash_command='date',
    dag=dag)

Running this DAG through the web-ui using the "run now" button produces the following exception:

Running with the scheduler isn't much better (below is the exception thrown by the scheduler)
