Ariel Weisberg commented on CASSANDRA-14155:
--------------------------------------------
This is failing in the rolling upgrade case. [There is a 60 second sleep in the
test between every node upgrade to the newer
version.|https://github.com/apache/cassandra-dtest/blob/master/upgrade_tests/upgrade_through_versions_test.py#L344]
It seems unlikely A or B would not have gossiped with C before C is upgraded.
I got the entire endpoint state map.
