---------------------------------
Hi [~martijnvisser] [~Sergey Nuyanzin] [~mapohl]
Sorry it wasn't fully fixed,
SourceCoordinatorAlignmentTest.testWatermarkAlignmentWithTwoGroups fails now. I
have analyzed it, and created FLINK-32495. Let's follow it there.
BTW, FLINK-32495 doesn't happen every time, I just run CI at master branch
before merging. I merged them for master, release-1.16 and release-1.17 after
the master CI passed.
I will submit multiple PRs in the future for each release branch, and check all
CIs. Try to avoid it in the future.
Sorry again for this mistake.
