> Key: AIRFLOW-271
> URL: https://issues.apache.org/jira/browse/AIRFLOW-271
> Project: Apache Airflow
> Issue Type: Bug
> Components: scheduler
> Affects Versions: 1.7.1
> Reporter: TERESA YAN
> Priority: Major
> Fix For: 1.7.1.2
>
> Attachments: feed_scheduler_template.py
>
>
> 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
> }
> 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
