<!-- Greeting --> Hi @wanwancloud! I'm [Dosu](https://go.dosu.dev/dosubot) and I’m helping the incubator-hugegraph team. <!-- Answer --> 你的配置和日志里出现的 raft 相关参数（如 raft.endpoint、raft.election_timeout_ms 等）已经被废弃，HugeGraph 现在只识别注册在 OptionSpace 里的参数，未注册的会被直接警告为“redundant”[参考](https://github.com/apache/incubator-hugegraph/blob/337dc86567834acd717a2240a79fef2815d4bb6f/hugegraph-commons/hugegraph-common/src/main/java/org/apache/hugegraph/config/HugeConfig.java)。建议只保留官方文档和源码里明确支持的 raft 配置项，比如 raft.mode、raft.safe_read、raft.group_peers、raft.election_timeout、raft.rpc_connect_timeout、raft.rpc_timeout 等，参数名和单位要与源码一致（比如 raft.election_timeout，单位毫秒，默认 10000）。 RocksDB 分布式部署常见问题包括 OOM 导致数据损坏、SST 文件 ahead of WALs、lock 文件未释放等。建议： 1. JVM 内存调大（-Xmx/-Xms）， 2. 优化 rocksdb.write_buffer_size、rocksdb.max_write_buffer_number、rocksdb.block_cache_size， 3. 多盘环境用 rocksdb.data_disks， 4. 定期 compact， 5. 遇到 SST/WAL 不一致可用 ldb repair 工具修复， 6. lock 问题需确保所有进程都已关闭再初始化，必要时手动删除 lock 文件（注意数据安全）[参考](https://github.com/apache/incubator-hugegraph/issues/2762)。 Cassandra 后端 netty-all 兼容性问题，HugeGraph 1.5.0 推荐用 Cassandra 3.1x，4.x 存在 breaking change，建议降级到 3.1x 版本[参考](https://github.com/apache/incubator-hugegraph/issues/2768)。1.7 及以后 Cassandra 将不再是主力支持后端，官方推荐生产环境用 HStore（Raft+RocksDB 组合），未来也会逐步淘汰 HBase/Cassandra[参考](https://github.com/apache/incubator-hugegraph/discussions/2737)。 如果你需要分布式高可用，建议直接用 HStore（Raft+RocksDB），配置 raft.group_peers、raft.mode=true 即可，避免使用已废弃参数。遇到 raft 相关异常，需确保所有节点 raft 配置一致，路径可写，端口无冲突，且依赖包版本匹配[参考](https://github.com/apache/incubator-hugegraph/issues/2725)。 如需进一步定位 RocksDB 或 Cassandra 的具体报错，请补充详细的错误日志。 <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
