是的，Java驱动程序的4.x版本与Cassandra 3.0和3.11集群兼容。

有关详细信息，请参阅Java驱动程序兼容性矩阵。

根据我所了解的情况，如果您的集群负载过重，可能会导致超时异常。祝好！

英文:

Yes, version 4.x of the Java drivers are compatible with Cassandra 3.0 and 3.11 clusters.

Without knowing details of the issue you are facing, my best guess is that your cluster is overloaded leading to the timeout exceptions. Cheers!
