[jira] [Created] (AIRFLOW-271) schedule_interval at a particular time behaves strangely

TERESA YAN created AIRFLOW-271:
----------------------------------

             Summary: schedule_interval at a particular time behaves strangely
                 Key: AIRFLOW-271
                 URL: https://issues.apache.org/jira/browse/AIRFLOW-271
             Project: Apache Airflow
          Issue Type: Bug
          Components: scheduler
    Affects Versions: Airflow 1.7.1
            Reporter: TERESA YAN
             Fix For: Airflow 1.7.1.2


I have created a dag with the following configs in a python dag script.

default_args = {
    'owner': 'airflow',
    'depends_on_past': False,
    'start_date': datetime(2016,6,20),
    'email': email_list,
    'email_on_failure': True,
    'email_on_retry': True,
    'retries': 3,
    'retry_delay': timedelta(minutes=2),
    'provide_context': True
    # 'queue': 'bash_queue',
    # 'pool': 'backfill',
    # 'priority_weight': 10,
    # 'schedule_interval': timedelta(1),
    # 'end_date': datetime(2016, 1, 1),
}

dag = DAG('feed_scheduler_template', default_args=default_args, schedule_interval="01 16 * * *")

When I run the scheduler,  it gives a strange behavior, for example today is 6/20 19:30  (I clear the db when I run the scheduler), start_date is 6/20

It will start running for the following three timestamps in the logs directory

data@dp-i-54a2648f:~/airflow/logs/feed_scheduler_template $ ls -l send
total 12
-rw-rw-r-- 1 data data 3099 Jun 22 19:30 2016-06-20T00:00:00
-rw-rw-r-- 1 data data 3100 Jun 22 19:30 2016-06-20T16:01:00
-rw-rw-r-- 1 data data 3100 Jun 22 19:30 2016-06-21T16:01:00

The question is
1.  Why is 2016-06-20T00:00:00 at 0 hour 0 minute get executed because I only want 16:01.
2.  I never get the 2016-06-22T16:01:00 run although my machine time already pass that 16:01 hour on June 22.

Any idea?

Thanks so much
