YXWisaboy opened a new issue, #1898:
URL: https://github.com/apache/incubator-hugegraph/issues/1898
### Problem Type (问题类型)
server status (启动/运行异常)
### Before submit
- [X] 我已经确认现有的 [Issues](https://github.com/hugegraph/hugegraph/issues) 与 [FAQ](https://hugegraph.github.io/hugegraph-doc/guides/faq.html) 中没有相同 / 重复问题
### Environment (环境信息)
- Server Version: v0.11.x
- Backend: RocksDB x nodes, HDD or SSD
- OS: xx CPUs, xx G RAM, Centos 7.x
- Data Size: xx vertices, xx edges <!-- (like 1000W 点, 9000W 边) -->
### Your Question (问题描述)
将数据从mysql数据库导入，配置存储后端也是mysql情况下，
在用load工具添加节点元信息时，出现找不到groovy类的错误，不知道是不是版本匹配问题，jdk使用的也是1.8，还是中文问题？
添加节点执行的groovy语句：
schema.vertexLabel("car_model").usePrimaryKeyId().properties("car_model_id","车型配置","经销商报价","官方指导价","生产厂商","大中小等级","能源类型","上市时间","发动机参数","最大功率","发动机最大功率"···············,"大灯高度调节","大灯清洗功能","车内氛围灯","灯光特色功能","大灯延时关闭","前大灯雨雾模式","电动车窗1","电动车窗2","车窗一键升降","车窗防夹手功能","外后视镜功能1","外后视镜功能2","外后视镜功能3").primaryKeys("car_model_id").ifNotExist().create();
属性共254个

### Vertex/Edge example (问题点 / 边数据举例)

有可能是groovy限制了动态参数长度问题，可以尝试将参数使用中括号:
```java
schema.vertexLabel("car_model").usePrimaryKeyId().properties(["p1", "p2", "p3...").ifNotExist().create();
```

感谢回复，我把属性数量削减到200以下时，可以成功将节点数据导入了，但边数据导入仍存在问题
我的后端为mysql，数据形式如下
我的schema文件中关于节点与边的定义如下：
schema.vertexLabel("car_brand").usePrimaryKeyId().properties("car_brand_name").primaryKeys("car_brand_name").ifNotExist().create();
schema.vertexLabel("car_model").usePrimaryKeyId().properties("car_model_id","车型配置","经销商报价",········,"110V/220V/230V电源插座","行李舱12V电源接口").primaryKeys("car_model_id").ifNotExist().create();
schema.edgeLabel("product").sourceLabel("car_brand").targetLabel("car_model").ifNotExist().create();
关于边的映射如下：
{
"version": "2.0",
"structs": [
{
"id": "3",
"skip": false,
"input": {
"type": "jdbc",
"vendor":"MySQL",
"driver": "com.mysql.cj.jdbc.Driver",
"url": "jdbc:mysql://····",
"database": "···",
"table": "····",
"username": "····",
"password": "····"
},
"vertices": [
],
"edges": [
{
"label": "product",
"source": ["id"],
"target": ["manufacturer"],
"field_mapping": {
"id": "car_model_id",
"manufacturer": "car_brand_name"
},
"value_mapping": {},
"selected": [],
"ignored": [],
"null_values": [
""
],
"update_strategies": {}
}
]
}
]
}
log中的报错如下：

关于第二个边解析错误问题，请检查下error-data-log目录下实际的错误数据内容，确保car_brand（manufacturer）实际存在。
