Marcus Eriksson commented on CASSANDRA-14238:
---------------------------------------------
this only fails on 2.2, and most often because the DeletionTime is initialized
with a negative local deletion time due to the randomness when corrupting the
files. Can't reproduce on 3.0+
patch https://github.com/krummas/cassandra/commits/marcuse/14238 which hard
codes the random seed to something I've tested works (ran the test in a loop
for 10+ minutes)
test run on circle:
