URL: https://github.com/apache/incubator-hugegraph/issues/1974

   ### Bug Type (问题类型)
   
   other exception / error (其他异常报错)
   
   ### 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: v0.11.2
   - Backend: HBase
   - Data Size:  1000 vertices
   - java：1.8
   
   
   ### Expected & Actual behavior (期望与实际表现)
   
   期望正常批量写入数据至hugegraph，在代码中使用了addVertices(List<Vertex> vertices)方法批量写入。
   但是出现了如下异常：
   class java.lang.ClassCastException: java.util.ArrayList cannot be cast to 
java.lang.Integer

   ### Vertex/Edge example (问题点 / 边数据举例)
   
   ```javascript
   经过排查之后发现，我修改了conf目录下的rest-server.properties文件，添加了如下两个参数：
   batch.max_write_ratio=100
   batch.max_write_threads=0
   当我将文件中的这两个参数注释掉之后，批量写入数据addVertices便不会出现 java.util.ArrayList cannot be cast 
to java.lang.Integer异常了，不知道这算不算一个Bug
   ```
   
   
   ### Schema [VertexLabel, EdgeLabel, IndexLabel] (元数据结构)
   
   _No response_
