Adding newsfragments for removed executors -- Sequential & Debug

[amoghrajesh]

#48579 and #48528 removed Sequential and Debug Executors. We should add significant newsfrags for these as it is a behaviour change for end users.

Is it possible for user to set something to Sequential/Debug Executor in code or config?

[amoghrajesh]

Nah I do not think so from looking at the code

[amoghrajesh]

@Lee-W there is a possibility of doing something of that sort in "core \ executor" config but we shield it now and do not allow it.

[Lee-W]

Nah I do not think so from looking at the code

How do people set it to Sequential / Debug in the past?

[amoghrajesh]

cc @eladkal maybe you are the right person for this, can these executors be set anywhere in the code / config?

[amoghrajesh]

Nah I do not think so from looking at the code

It was using either the config or env variable: https://airflow.apache.org/docs/apache-airflow/stable/core-concepts/executor/index.html

Then I think we might still need a config rule then?

[amoghrajesh]

Wondering that too. Is it possible to have a rule to override either of those to LocalExec?

We could add it to the airflow config lint section. Then, we'll figure out how we do it later.

[amoghrajesh]

@Lee-W let me do that yeah

[amoghrajesh]

@eladkal that change has been made. I am getting the debugexecutor doc refs removed too.
