Looks like the test takes too long to run?

Maybe just running to much time / a deadlock or other bug...I don't know :(

[westonpace]

kDefaultAssertFinishesWaitSeconds is generally long enough that even CI machines will finish by then. So I think deadlock seems likely :(

[westonpace]

I've reproduced this. It is a deadlock. It appears that, in some cancel situations, GroupByNode is not properly marking it's finished future as complete. I can probably spot fix this if we need to but it is fixed more categorically by #15253 (I'm attempting to reproduce on that branch and so far have not been able to so that is a good sign). If it appears that #15253 is not going to merge before the release then I will fix this individually (feel free to ping me if it seems like I am forgetting).

[mapleFU]

Please go ahead, I just blocked by CI

By the way, I meet another timeout, but I don't understand why: https://github.com/apache/arrow/actions/runs/3886295191/jobs/6631229773

[westonpace]

I don't think #15253 will merge in time. I am going to try and put in a more targeted fix today.

Hi westonpace, did you solve this issue?

Thanks for the reminder, I had forgotten.
