<!-- Answer --> 感谢确认这是一个全新集群。既然不是旧版本数据升级的问题，那这很可能是 hstore 后端在集群初始化阶段的一个 bug 或时序问题。 根据代码分析，有几个可能的原因： **1. Store 节点未完全就绪时 Server 就开始查询数据** `ServerInfoManager` 在启动时会立即尝试读写 `server-1` 系统顶点。如果 hstore 的分区分配还未完成，写入可能产生不完整/损坏的数据，后续读取就会出现 varint 解析错误。HugeGraph 存在已知的分区分配超时问题 [[1]](https://github.com/apache/hugegraph/issues/2999)。 **2. 节点间时钟不同步** `ServerInfoManager` 对时钟偏差有严格要求（>30秒会抛异常）[[2]](https://github.com/apache/hugegraph/blob/9126c80e414c073b60fc074361b211cfb409e0eb/hugegraph-server/hugegraph-core/src/main/java/org/apache/hugegraph/task/ServerInfoManager.java#L110-L114)，时钟偏差也可能导致初始化异常。 **建议排查步骤：** 1. **确保正确的启动顺序并等待就绪**：先启动所有 PD 节点 → 等 PD leader 选举完成 → 启动所有 Store 节点 → **等 Store 日志确认分区分配完成** → 最后再启动 Server 节点 2. **检查三个节点的时钟同步**： ```bash # 在三个节点上分别执行，确认时间差在几秒以内 date # 确保 NTP/chrony 服务正常运行 systemctl status chronyd ``` 3. **清理数据后重试**：停止所有服务，清空 hstore 数据目录（`pd_data` 以及 Store 的数据目录），然后按上述顺序重新启动 4. **确认所有组件版本一致**：PD、Store、Server 三个组件必须来自同一个 master commit 编译 5. **验证是否为 hstore 特有问题**：如果方便，可以临时改用 RocksDB 后端（单节点模式）测试，如果 RocksDB 正常启动，则可以确认是 hstore 后端的序列化 bug 另外，日志中的 Jersey 错误 `"Error occurred when processing a response created from an already mapped exception"` 是 Raft leader 选举期间的正常瞬态现象 [[3]](https://github.com/apache/incubator-hugegraph/issues/2787)，与序列化错误无关，可以忽略。 如果清理数据并严格按顺序启动后仍然复现，这很可能是 hstore 后端在 1.7.0 master 分支中的序列化 bug——hstore 集成层存在一些已知的[不完整之处](https://github.com/apache/hugegraph/blob/9126c80e414c073b60fc074361b211cfb409e0eb/hugegraph-server/hugegraph-core/src/main/java/org/apache/hugegraph/backend/serializer/BinarySerializer.java#L442)。建议在这个 issue 中补充 PD 和 Store 的启动日志，以便进一步定位。 <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot?utm_source=github&utm_medium=bot-comment&utm_campaign=github-comment-footer-20260415&utm_content=reply-with-mention&utm_term=apache%2Fhugegraph).* --- Docs are dead.
