title: Spring Boot 2.3.1.Release and Cassandra DriverTimeout issue
body: <p>I am upgrading to Spring boot version 2.3.1.Release. So, there is a major change in Spring Data Cassandra due to Java driver version upgrade to v4. I am stuck on application startup because there is a DriverTimeout exception being thrown:</p>
  <pre><code> com.datastax.oss.driver.api.core.DriverTimeoutException: [s0|control|id: 0x8572a9d7, L:/My_IPv4:Random_Port - R:/Cassandra_Server:Port] Protocol initialization request, step 1 (OPTIONS): timed out after 500 ms
  </code></pre>
  <p>My cassandra configuration:</p>
  <pre><code>    @Bean(name = &quot;mySession&quot;)
       @Primary
        public CqlSession session() {
          
           String containerIpAddress = getContactPoints();
           int containerPort = getPort();
           InetSocketAddress containerEndPoint = new InetSocketAddress(containerIpAddress, containerPort);
           
           return CqlSession.builder().withLocalDatacenter(getLocalDataCenter())
                  .addContactPoint(containerEndPoint)
                  .withAuthCredentials(dbProperties.getCassandraUserName(), dbProperties.getCassandraPassword())
                  .withKeyspace(getKeyspaceName()).build();
      }
  </code></pre>
  <p>I have also tried using DriverConfigLoader option by explicitly setting connection timeout as:</p>
  <pre><code>     @Bean(name = &quot;mySession&quot;)
       @Primary
        public CqlSession session() {
          
           String containerIpAddress = getContactPoints();
           int containerPort = getPort();
           InetSocketAddress containerEndPoint = new InetSocketAddress(containerIpAddress, containerPort);
           
           DriverConfigLoader loader =
                   DriverConfigLoader.programmaticBuilder()
                       .withDuration(DefaultDriverOption.CONNECTION_CONNECT_TIMEOUT, Duration.ofSeconds(5))
                       .build();
  
           return CqlSession.builder().withLocalDatacenter(getLocalDataCenter())
                   .withConfigLoader(loader)
                  .addContactPoint(containerEndPoint)
                  .withAuthCredentials(dbProperties.getCassandraUserName(), dbProperties.getCassandraPassword())
                  .withKeyspace(getKeyspaceName()).build();
      }
  </code></pre>
  <p>, but to no avail and same exception is being thrown. My current Spring boot version is 2.2.0.Release and I am not even specifying any timeout there and its working fine. How can this issue be fixed?</p>
