Ruslan Dautkhanov updated AIRFLOW-1176: --------------------------------------- Description: Gantt visualization is brojen. It used to work on a ~month older Airflow snapshot. See attached screenshot. !Gantt.png! - It just doesn't show anything (it used to show all >40 operators correctly) - time scale is shifted so almost no visible It is a `@once` DAG.. I noticed Airflow has a number of issues around `@once` DAG, so decided to mention. {noformat} main_dag = DAG( dag_id = 'DISCOVER-Oracle-Load-Mar2017-v1', default_args = default_args, # dafeult operators' arguments - see above user_defined_macros = dag_macros, # I do not get different between ## params = dag_macros, # user_defined_macros and params # start_date = datetime.now(), # or e.g. datetime(2015, 6, 1) # 'end_date' = datetime(2016, 1, 1), catchup = False, # Perform scheduler catchup (or only run latest)? # - defaults to True schedule_interval = '@once', # '@once'=None? # doesn't create multiple dag runs automatically concurrency = 3, # task instances allowed to run concurrently max_active_runs = 1, # only one DAG run at a time dagrun_timeout = timedelta(days=4), # no way this dag should ran for 4 days orientation = 'TB', # default graph view ) {noformat} was: Gantt visualization is brojen.
