Gerard Toonstra commented on AIRFLOW-1147:
------------------------------------------
The example uses an interval of 1440 minutes, or 24 hours. How long did you
wait until you come to the conclusion that the scheduler doesn't work?
This was raised 2 days ago and the scheduler would only pick this up every 24
hours.
To be able to test this, you could copy this dag, change the dag-id to
something different (you should never change intervals of dags that have been
deployed/run), and then change the interval to something like 2 minutes. With
those settings, do you still see that the dag doesn't get processed every 2
minutes? What's the output of the scheduler in that case?
When you have a start_date of today, the first time the dag runs is on
start_date+interval, so the day after, because it obviously doesn't have any
data prior to that.
Let us know!

> Project: Apache Airflow
> Issue Type: Bug
> Components: scheduler
> Affects Versions: Airflow 1.8
> Environment: CentOS running on 128 GB ram
> Reporter: Mubin Khalid
> Priority: Critical
> Labels: documentation, newbie
> Original Estimate: 24h
> Remaining Estimate: 24h

> I've created some `DAG`s, and I tried to put it on scheduler. I want to run
> all the tasks in the DAG after exact 24 hours.
> I tried to do something like this.
> {code}
> DEFAULT_ARGS = {
> 'owner' : 'mubin',
> 'depends_on_past' : False,
> 'start_date' : datetime(2017, 4, 24, 14, 30),
> 'retries' : 5,
> 'retry_delay' : timedetla(1),
> }
> SCHEDULE_INTERVAL = timedelta(minutes=1440)
> # SCHEDULE_INTERVAL = timedelta(hours=24)
> # SCHEDULE_INTERVAL = timedelta(days=1)
> dag = DAG('StandardizeDataDag',
> default_args = DEFAULT_ARGS,
> schedule_interval = SCHEDULE_INTERVAL
> )
> {code}
> I tried to put different intervals, but not any working. However if I try to
> reset db {code} airflow resetdb -y {code} and then run {code} airflow
> initdb {code} , it works for once. then after that, scheduler isn't able to
> run it.
> PS. {code} airflow scheduler {code} executed from {code} root {code}
