Spark写入Dataset对象到图数据库：

Caused by: java.lang.AbstractMethodError: com.vesoft.nebula.connector.writer.NebulaVertexWriterFactory.createDataWriter(II)Lorg/apache/spark/sql/sources/v2/writer/DataWriter;

spark connector 版本号，spark 版本号，Nebula 版本号的都补充一下下。

3

spark 2.4.0 ，spark-connector 3.0.0 nebula 3.0.0

:thinking: 我记得之前 spark connector 的作者说过，是要 2.4.0 以上的 spark 版本，你这边方便升级下 spark 版本吗

5

我改成 spark：2.4.4 spark-connector 3.0.0 nebula 3.0.0 还是出现这个问题

:thinking: 要不你看看这个帖子
