      Description

      test_simple_strategy_users and test_network_topology_strategy_users are failing on 3.0 and trunk, on Windows and Linux. Logs for test_simple_strategy_users are attached.

      Both tests are consistently seeing timeouts, whether in the form of OperationTimedOut or ReadFailure exceptions. Example stacktrace is

      Traceback (most recent call last):

      The tests are consistently failing on 3.0. They consistently pass on 2.2. Here is a link to a failure on cassci. http://cassci.datastax.com/job/cassandra-3.0_dtest/119/testReport/consistency_test/
