我写了一个 AirFlow DAG 如下 -
default_args = {
'owner': 'airflow',
'depends_on_past': False,
'start_date': datetime(2016, 7, 5),
'email': ['airflow@airflow.com'],
'email_on_failure': False,
'email_on_retry': False,
'retries': 1,
'retry_delay': timedelta(seconds=30),
# 'queue': 'bash_queue',
# 'pool': 'backfill',
# 'priority_weight': 10,
# 'end_date': datetime(2016, 1, 1),
}
dag = DAG(
'test-air', default_args=default_args, schedule_interval='*/2 * * * *')
.................
.................
{{Tasks}}
根据上面的配置,作业应该每隔一分钟运行一次。但相反,它显示在输出下方
airflow scheduler -d test-air

有人可以在这里指导我吗?
