Ekaterina Dimitrova commented on CASSANDRA-17882:
-------------------------------------------------
Looking into the test it seems to me nothing more than a timing issue.
If we reduce the TTL to 5 seconds we can reproduce the failure so I suggest we
just raise the TTL from 20 to 30 to prevent flakiness.
I didn't run repeatedly the test with the increased TTL in CircleCI as it was
not failing there even with the old value.
4.1 -

and

1000 runs on clean 4.1 without the patch
4.0 - [1000 runs
|https://app.circleci.com/pipelines/github/ekaterinadimitrova2/cassandra?branch=clean-4.0]
running each repeatable job on clean 4.0
I actually decided to increase also the next UPDATE statement TTL to 30 too,
just in case so we don't have to revise the test again in two days.
I looped the test locally a few times with no issues.
