问题-无法使用Spark Cassandra连接器1.5.0连接Cassandra 3.0
背景-我试图通过使用提供的Spark cassandra连接器1.5.0从Spark 1.5.0连接Cassandra 3.0，但我得到以下错误-

根据DataStax Spark Cassandra连接器document，它表示Spark连接器1.5可以从Spark 1.5.0/1.6.0用于Cassandra 3.0。
你能告诉我我是不是漏掉了什么步骤吗？

尝试过的方法

1.我尝试从Spark流和核心jar中排除Guava依赖项
1.在“pom.xml”中添加了单独的Guava依赖项
先谢谢你。
