Scala 不支持Cassandra-SERIAL作为条件更新提交一致性

我确实从Spark（2.0.2）写到Cassandra（3.7）：

Spark cassandra连接器（版本2.0.0-M3）一致性配置：

spark.cassandra.output.consistency.level ONE

它在一段时间内运行良好，但现在开始失败，只有以下例外：

ERROR writer.QueryExecutor: Failed to execute: com.datastax.spark.connector.writer.RichBoundStatement@6ad8868c
com.datastax.driver.core.exceptions.InvalidQueryException: SERIAL is not supported as conditional update commit consistency. Use ANY if you mean "make sure it is accepted but I don't care how many replicas commit it for non-SERIAL reads"

如果您有任何解决方法的建议，我们将不胜感激。提前谢谢

someRdd中有什么？我可以想象这对于某些集合是不可能的。有一些例子是这个

案例类SomeObj（value:String，name:String，id:String，ts:Timestamp，tag:String，valid:Boolean）扩展了可序列化的
表描述
创建表个人\u id（名称文本、值文本、id文本、ts时间戳、标记文本、主键（（名称、值）、id））；
Ok对此不确定，我会向Spark Cassandra Connector提交Jira您使用的是什么版本的datastax驱动程序？
