Airflow not scheduling Correctly Python

Question

Code:

Python version 2.7.x and airflow version 1.5.1

my dag script is this

from airflow import DAG
from air         


        

Answer 1

Because the start time(2015-10-13 00:00) less than now time, it triggers the airflow backfill. It will run from 2015-10-13 00:00 when every seconds the airflow scheduler detected(its the Start Date), but Execution Date is between 5 min(task interval time).

See the log name:

See the create time of logs:
