Re: Task got executed even when it's only immediate parent was in upstream failed state


Hi Fokko,

This would be difficult to test. I am not sure of the condition when it
occurred. Our DAG runs nightly and this has happened once in the past three
months.

If this is something that has been identified and fixed in 1.10, I can make
an attempt to upgrade it. But I did not see anything related to this in the
changelog.






Regards,

Abhishek

Hi Abhishek,

Do you think it would be difficult to verify if this behavior still exists
in 1.10? Maybe write a dummy dag, and run it using Docker.

Cheers, Fokko
