Stefan Miklosovic updated CASSANDRA-17144:
------------------------------------------
Test and Documentation Plan: updated dtest
Status: Patch Available (was: In Progress)
https://github.com/apache/cassandra-dtest/pull/197
enabledgossip / disablegossip takes some time, the commands are non-blocking
but it takes time to fully enable / disable. The test fails sometimes because
gossip was not shut down in a timely manner before another set of inserts in
executed so there will be hints done for that as well and then it fails the
asserts that such set of inserts is not there.
I have tested this in circle 100x and it was consistently not failing.
