             Summary: Dtest Failure 3.0: consistency_test.py:TestAccuracy
                 Key: CASSANDRA-10224
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10224
             Project: Cassandra
          Issue Type: Test
            Reporter: Philip Thompson
             Fix For: 3.x, 3.0.x


{{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
{code}
Traceback (most recent call last):
  File "/home/automaton/cassandra-dtest/consistency_test.py", line 452, in run
    valid_fcn(v)
  File "/home/automaton/cassandra-dtest/consistency_test.py", line 401, in validate_users
    outer.update_user(sessions[s], n, age, write_cl, serial_cl, age - 1)
  File "/home/automaton/cassandra-dtest/consistency_test.py", line 138, in update_user
    session.execute(statement)
  File "/usr/local/lib/python2.7/dist-packages/cassandra/cluster.py", line 1615, in execute
    result = future.result(timeout)
  File "/usr/local/lib/python2.7/dist-packages/cassandra/cluster.py", line 3154, in result
    raise self._final_exception
ReadFailure: code=1300 [Replica(s) failed to execute read] message="Operation failed - received 3 responses and 2 failures" info={'failures': 2, 'received_responses': 3, 'required_responses': 4, 'consistency': 'QUORUM'}
{code}

The tests are consistently failing on 3.0. They consistently pass on 2.2. Here is a link to a failure on cassci.
