什么是com.datastax.oss版本与java8和spark3.2.0兼容?我不知道哪个版本的spark和springboot兼容。以下代码是否正确?如果是,则存在的依赖性是否有效?我想在cassandra中使用spark选择query。这是我目前使用的代码:
java.lang.NoClassDefFoundError: com/datastax/oss/driver/internal/core/util/collection/SimpleQueryPlan

此代码显示错误:

兼容性矩阵可以在这里找到:
https://github.com/datastax/spark-cassandra-connector#version-compatibility
我认为你有一个依赖性问题与java驱动程序4.9.0。看起来最低驱动程序版本应该是4.13.0。
