------------------------------
[~milton0825] are you familiar with backfilling issues regarding specific crons?
> Support for non contiguous schedules
> ------------------------------------
>
> Key: AIRFLOW-569
> URL: https://issues.apache.org/jira/browse/AIRFLOW-569
> Project: Apache Airflow
> Issue Type: Bug
> Components: scheduler
> Affects Versions: 1.7.1.2
> Reporter: Martin Grayson
> Priority: Major
>
> I've recently created a dag that I want to run hourly, with the exception of
> a maintenance window during the night.
> To handle this, I use the cron syntax to specify the hours I wish to run.
> {code}schedule_interval='0 6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22 * *
> *'{code}
> i.e. Don't run 23:00-05:00
> This works well and actually executes as desired. The only issue is with
> backfilling.
> When I initially deploy my dag, the scheduler creates the expected series of
> dag runs each hour since the start date, excluding the hours not in my
> schedule. However, when it comes to create the 06:00 execution, it simply
> fails the dag (and all subsequent) - I'm not sure why as I cant see any
> failure in the logs. The dag simply gets marked as failed.
> Is this a bug or something to be expected?
> Thanks,
> Martin
