Matthias Pohl commented on FLINK-33012:
---------------------------------------
I added 1.18, 1.17 and 1.16 as affected versions and lowered the priority to
{{Major}} to reflect that it's not a constant problem. We can increase the
priority again if it pops up more regularly (but which I don't assume).
> LeaderElectionTest.testHasLeadership fails on AZP due to fsync not coming
> back fast enough
