Ekaterina Dimitrova commented on CASSANDRA-17798:
-------------------------------------------------
I do not think that only the duration is playing a role in these failures.
No matter what a number I set the test is failing in both 4.0 and 4.1. I got
suspicious and went back to 4.0 rc2 and it is still flaky there. I wouldn't be
surprised if it was introduced flaky in alpha1 but I didn't manage to build
locally from that commit as too many changes happened to our builds since then
and spending too much time on that didn't seem worth it to me.
In other words - this seems as a long time flaky test, no regression or 4.1
blocker. We should look into it but it is not a priority for the 4.1 release.
Removing from the blockers list and will get back to it later.
