<!-- Greeting --> Hi @hahahahbenny! I'm [Dosu](https://go.dosu.dev/dosubot) and I’m helping the incubator-hugegraph team. <!-- Answer --> 你遇到的报错是因为 example.groovy 脚本和 empty-sample.groovy 的作用完全不同。empty-sample.groovy 只是一个最小化的 Gremlin Server 初始化脚本，不依赖 HugeGraph 的内部类或 API，适合直接作为 ScriptFileGremlinPlugin 的初始化脚本。而 example.groovy 是一个完整的数据和 schema 初始化脚本，需要直接访问 HugeGraph 的 API 和自定义类，只能在特定的预加载（preload）场景下使用，否则会因为类加载、依赖或上下文不对导致 GremlinScriptEngine 初始化失败，出现你看到的 BackendStoreProvider/rocksdb 相关报错（比如“Already registered option holder: rocksdb” 和 “Exists BackendStoreProvider: rocksdb”）[example.groovy 脚本内容](https://github.com/apache/incubator-hugegraph/blob/337dc86567834acd717a2240a79fef2815d4bb6f/hugegraph-server/hugegraph-dist/src/assembly/static/scripts/example.groovy)。 HugeGraph 的启动脚本（start-hugegraph.sh）在 preload=true 时会自动做特殊处理，把 example.groovy 复制为 example-preload.groovy，并去掉部分不兼容的行，然后才注入到 gremlin-server.yaml 里。正常启动时只会用 empty-sample.groovy，避免出错[启动脚本逻辑](https://github.com/apache/incubator-hugegraph/blob/337dc86567834acd717a2240a79fef2815d4bb6f/hugegraph-server/hugegraph-dist/src/assembly/static/bin/start-hugegraph.sh)。 所以，不能直接把 gremlin-server.yaml 里的 empty-sample.groovy 改成 example.groovy，否则会导致 Gremlin Server 初始化失败。如果你需要批量导入 schema 和数据，建议用 preload 方式或用 REST API/console 工具导入。 相关讨论和报错分析可参考：[1](https://github.com/apache/incubator-hugegraph/issues/2766) [2](https://github.com/apache/incubator-hugegraph/issues/2768)。 <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
