Berenguer Blasi commented on CASSANDRA-18707:
---------------------------------------------
bq. 4.0 is a stable branch where we do not see many changes
Correct. The problem is that we have no insight as to what is happening in
jenkins at the time. It might hit it as well
bq. we see this timeout with a specific test, and not with many, which makes it
suspicious.
I disagree here. I have seen schema changes many times go over 60s in jenkins.
That was a common scenario when we were on the 4.0 flaky fixing frenzy and
that's why at the time I did already propose to raise timeouts already. That
was declined and I found myself debugging through logs the same problem 2 or 3
extra times. This is just another one.
bq. not waste time from scratch
Correct. But you you just have an indication of what have happened. You still
have to wade through logs to confirm it is indeed the same scenario.
bq. In Python DTests we opted to raise the timeout
Correct and I think it was a good move. I will change the 140s to 120s for
consistency and OCD lol
Thanks I'll put PRs up
