### Problem Type (问题类型) other exception / error (其他异常报错) ### Before submit - [X] 我已经确认现有的 [Issues](https://github.com/apache/hugegraph/issues) 与 [FAQ](https://hugegraph.apache.org/docs/guides/faq/) 中没有相同 / 重复问题 (I have confirmed and searched that there are no similar problems in the historical issue and documents) ### Environment (环境信息) - Server Version: 0.11.2(Apache Release Version) - Cassandra 3.11.9 - Backend: RocksDB x nodes, HDD or SSD - OS: xx CPUs, xx G RAM, Ubuntu 2x.x / CentOS 7.x - Data Size: xx vertices, xx edges <!-- (like 1000W 点, 9000W 边) --> ### Your Question (问题描述) 1.底层存储的Cassandra发生迁移之后，访问的地址不变 2.迁移之后底层的表目前都存在 库名：cassandra01 3.启动hugegraph连着Cassandra无法启动 4.详细报错如下：Dec 10, 2024 6:27:28 AM org.glassfish.grizzly.http.server.NetworkListener shutdownNow INFO: Stopped listener bound to [0.0.0.0:8080] 2024-12-10 06:27:28 6591 [main] [ERROR] com.baidu.hugegraph.dist.HugeGraphServer [] -
