Bolke de Bruin edited comment on AIRFLOW-168 at 5/26/16 7:20 AM: ----------------------------------------------------------------- The issue with double dagruns is due to this line: {code} # don't ever schedule prior to the dag's start_date if dag.start_date: next_run_date = dag.start_date if not next_run_date else max(next_run_date, dag.start_date) {code} which doesn't check if it was scheduled before. Will have a fix shortly. was (Author: bolke): The issue with double dagruns is due to this line: # don't ever schedule prior to the dag's start_date if dag.start_date: next_run_date = dag.start_date if not next_run_date else max(next_run_date, dag.start_date) which doesn't check if it was scheduled before.
