Ash Berlin-Taylor resolved AIRFLOW-3658. ---------------------------------------- Resolution: Duplicate > dag.get_run_dates() goes into infinite loop in case of missing date, cause by > DST switch > ---------------------------------------------------------------------------------------- > > Key: AIRFLOW-3658 > URL: https://issues.apache.org/jira/browse/AIRFLOW-3658 > Project: Apache Airflow > Issue Type: Bug > Components: DAG > Affects Versions: 1.10.1 > Environment: ubuntu 16.04 > python 3.6 > airflow 1.10.1 > Reporter: Peter Erben > Priority: Major > > In airflow.cfg the default_timezone is Europe/Budapest. In this timezone the > winter to summer DST switch happened on 2018-03-25 at 2am, when the hour > skipped to 3am. This means that 2018-03-25T02:00:00 is not a valid datetime > in that timezone. > I created a dag with these parameters: > > {code:java} > start_date = datetime(2018,3,25,0,0) - timedelta(days=2) > end_date = datetime(2018,3,25,0,0) + timedelta(days=2) > schedule_interval = '0 2 * * *' > {code} > > When I call dag.get_run_dates(), it never returns. > > Does this mean, that Airflow fails to schedule any tasks if I try to set the > Europe/Budapest timezone, and the daily time defined by the cronstring is > non-existent on the day of the DST switch? > -- This message was sent by Atlassian JIRA (v7.6.3#76005)
