Caleb Rackliffe commented on CASSANDRA-18564:
---------------------------------------------
bq. We could simply skip testing the cases where the query should timeout.
After all, those expected timeouts due to down replicas seem indistinguishable
from the timeouts produced by an overloaded CI environment. wdyt?
That seems reasonable to me.
