<!-- Answer --> 你的报错是因为 HugeGraph 在切换为 master 角色时，代码把 DistributedTaskScheduler 强制转换成了 StandardTaskScheduler，但实际当前环境下用的是 DistributedTaskScheduler，导致 ClassCastException。这通常出现在分布式或 HStore+PD 场景下，配置和代码对调度器类型的预期不一致。 HugeGraph 1.5.0 在 HStore+PD 场景下，集群调度完全由 PD 负责，master/worker 机制和 server.role 配置已经废弃，不再生效。如果你配置了 server.role=master，或者以“传统”分布式方式启动，可能会触发这类类型转换错误。建议： 1. 检查你的部署模式和 backend 配置，确认是否为 HStore+PD。如果是，去掉 server.role 相关配置，确保所有节点配置一致，完全交由 PD 管理集群角色和任务调度。 2. 如果不是 PD 场景，确保 schedulerType、server.role 等配置和实际部署模式一致，避免混用分布式和本地调度逻辑。 3. 这个问题在社区有类似反馈，属于 1.5.0 版本的已知类型安全隐患，建议关注后续版本修复或社区讨论进展。[相关讨论和说明](https://github.com/apache/incubator-hugegraph/issues/2833) 如需进一步排查，建议贴出 backend 相关配置和 PD 相关参数，确认集群实际运行模式。 <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot).* --- <sup>How did I do?
