   Actually, I tried to schedule another task to be 10 minutes between each other, I want the first task to start at 19:50.
   In the dag code (located in ~/airflow/dags/tutorial_v2.py), I set:
   -> start_date=datetime.datetime(2021, 4, 4, 19, 50)
   -> schedule_interval= '*/10 * * * *'
   The first task is succeeded but the other three of them are stuck in the state of "running".
   Some of the parameters I set in the dag code :
   default_args = {
   'owner': 'airflow',
   'depends_on_past': False,
   'wait_for_downstream' : False,
   'email': ['airflow@example.com'],
   'email_on_failure': False,
   'email_on_retry': False,
   'retries': 1,
   'retry_delay': timedelta(minutes=5),
   }
   
   I run these commands to schedule the dag:
   $ python ~/airflow/dags/tutorial_v2.py
   $ airflow db init
   $ airflow dags backfill dag_v6 -s 2021-04-04-19:50 -e 2021-04-06
   The tasks which have the execution time at future are succeeded but some of the tasks at the beginning are stuck in the state of "running" :+1:

   I don't understand why the scheduler skip some of the tasks, I would be very glad if you help me with this.
