为什么 Airflow 会因 INFO 崩溃 - “任务退出并返回代码 -9"? [英] Why is Airflow crashing with INFO - "Task exited with return code -9"?

问题描述

我有一个很大的 DAG 正在运行，但是它只是因为那条消息而停止，我无法弄清楚 Airflow 文档上的错误是什么.

I have a big DAG running, however it's stopping with just that message, I couldn't figure out what is the error on the Airflow docs.

如果这有所作为:我的 Airflow 在带有 Helm 图表的 Rancher 中运行.

If that makes difference: My Airflow is running in a Rancher with a Helm chart.

推荐答案

我想到了一种减少所有内存大小的方法.第一次尝试是加载一些行而不是所有行:

I thought about a way to reduce the size of all the memory possibilities. And the first try was load some number of lines instead of all the lines:

serverCursor = conn.cursor("serverCursor")
serverCursor.execute(f'''select * from {ORIGIN_SCHEMA}.{table};''')

df = []
while True:
  records = serverCursor.fetchmany(size=50000)
  df = df + records
  if not records:
    break
serverCursor.close()

解决了这个问题.
