LzMingYueShanPao opened a new issue, #1974:
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
   at com.baidu.hugegraph.exception.ServerException.fromResponse(ServerException.java:47)
   at com.baidu.hugegraph.client.RestClient.checkStatus(RestClient.java:93)
   at com.baidu.hugegraph.rest.AbstractRestClient.post(AbstractRestClient.java:198)
   at com.baidu.hugegraph.rest.AbstractRestClient.post(AbstractRestClient.java:178)
   at com.baidu.hugegraph.api.graph.VertexAPI.create(VertexAPI.java:56)
   at com.baidu.hugegraph.driver.GraphManager.addVertices(GraphManager.java:95)
   
   ### 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_

   如果只是注释了参数就没有异常, 应该是不符合预期的
   
   你可以看看最新的 0.12 或 master 分支编译后是否有同样的问题, 提供一下最小复现的方式
