private static ExternalResource initCassandraIfEnabled() {
    if (!enabled()) {
        // Return NOP resource (to avoid nulls)
        return new ExternalResource() {
            @Override/*from  ww w . ja va  2  s .c o  m*/
            public Statement apply(final Statement base, final Description description) {
                return super.apply(base, description);
            }
        };
    }

    String configurationFileName = null; // use default one
    // Apache Jenkins often fails with
    // CassandraAdapterTest Cassandra daemon did not start within timeout (20 sec by default)
    long startUpTimeoutMillis = TimeUnit.SECONDS.toMillis(60);

    CassandraCQLUnit rule = new CassandraCQLUnit(new ClassPathCQLDataSet("twissandra.cql"),
            configurationFileName, startUpTimeoutMillis);

    // This static init is necessary otherwise tests fail with CassandraUnit in IntelliJ (jdk10)
    // should be called right after constructor
    // NullPointerException for DatabaseDescriptor.getDiskFailurePolicy
    // for more info see
    // https://github.com/jsevellec/cassandra-unit/issues/249
    // https://github.com/jsevellec/cassandra-unit/issues/221
    DatabaseDescriptor.daemonInitialization();

    return rule;
