Paulo Motta commented on CASSANDRA-12057:
-----------------------------------------
I suspect {{dclocal_read_repair_chance}} (default=0.1) was triggered, that's
why node3 was repaired before repair was actually run, so I updated
{{dtest.create_cf}} to also set {{dclocal_read_repair_chance}} when
{{read_repair}} is specified (read_repair should be fully disabled for this
test).
This test was also breaking on Windows (CASSANDRA-12046), because it was
upgrading from 2.1.9 which is unsupported on Windows, so I updated it to
upgrade from 2.2.4 instead.
I also took the chance to move this test to {{upgrade_tests}} so it's run
together with the upgrade suite.
I submitted a [multiplexer
run|https://cassci.datastax.com/view/Parameterized/job/parameterized_dtest_multiplexer/154/]
to verify the changes indeed fixed the test flakiness.
In order to check the changes did not break existing tests, I also submitted a
[full dtest run on
trunk|http://cassci.datastax.com/view/Dev/view/paulomotta/job/pauloricardomg-trunkcopy-dtest/17/].
Will set to PA when CI and multiplexer results look good.
