Clearing task from List Task Instance page in UI does not also clear downstream tasks?

[aamster]

Apache Airflow version

2.6.3

What happened

Select tasks from List Task Instance page in UI and select clear
Only those tasks are cleared and downsteam tasks are not also cleared as they are in the DAG graph view

What you think should happen instead

downstream tasks should also be cleared

How to reproduce

Select tasks from List Task Instance page in UI for which there are downstream tasks and select clear

I think instead of automatically also clearing downstream tasks, maybe the modal from the grid/graph view should be displayed, giving the user the choice. For example:

@RNHTTR I removed the area:core label and put it area:UI. Please check if it sounds right.

I think that would be the ideal way though. It should not silently clear all the downstream tasks unless explicitly asked for.

I think we could discuss if it's a good idea to display the modal view from the List view.

Let's at least update this confirmation text to say that it includes downstream tasks?

Yes, this would be ideal. Not sure if we can reuse the same components unless we migrate this above screen to React?

[bbovenzi]

Yes, replacing this in react is a lot for now. let's at least update the confirmation modal since that already exists on the FAB model.

I would consider this a bug, not a new feature. I should never be uncertain what airflow is going to do. Here the obvious thing I would expect is that downstream tasks would be cleared like they are in other parts of the UI. It is common to need to resubmit groups of tasks and have downstream tasks automatically retriggered, but this does not happen. It is disoncerting that I have to constantly check to make sure airflow is functioning the way I expect for key business needs such as retriggering groups of tasks which it does not in this case.

Hey, I would like to try this one if that's ok
To make sure I get it right, expected behavior would be that downstream TIs are cleared + modal explicitely warns about it right?

@peloyeje yep, just assigned you!
