我已经在一个DAG中添加了一个任务,并一直试图在尚不存在的日期airflow backfill
进行任务。我给了命令--task_regex,--start_date和--end_date参数。
一切似乎都运行良好,但在某些DAG运行回填后,Airflow因此错误而崩溃:
[2019-06-06 12:13:25,378] {jobs.py:2521} INFO - Task exited with return code 0

有人知道会发生什么吗?我应该在后台启动此回填吗? (气流1.9)
答案 0 :(得分:0)
这看起来类似于本期所描述的 https://issues.apache.org/jira/browse/AIRFLOW-1482?attachmentSortBy=dateTime 当他们使用芹菜执行器时。
使用localexecution时有类似的问题,如果当前调度的回填任务失败,则回填将停止。也正在运行气流1.9。
