Tyler Hobbs commented on CASSANDRA-9117:
----------------------------------------
There are more dtests that are affected by this than I thought at first. This
also affects {{topology_test.TestTopology.decomission_test}},
{{secondary_indexes_test.TestSecondaryIndexes.test_6924_dropping_ks}},
{{incremental_repair_test.TestIncRepair.sstable_repairedset_test}}, and
{{counter_tests.TestCounters.upgrade_test}}. It's important that we get the
dtests into a reliable state soon, especially so that we can properly test
CASSANDRA-8099. I don't want to rush the review of CASSANDRA-8984 just so that
we can fix the dtests. Can you try to look into this (using the patch from
8984, if that's useful)?
