我正在尝试让 Cassandra 2.2.3（在 localhost 上运行）与 Spark 1.5.1 和最新版本的 spark-cassandra-connector (1.5.0-M2) 一起使用。
这是我正在使用的基本代码段。键空间和表已经创建。
import com.datastax.spark.connector._
import org.apache.spark.{SparkConf, SparkContext}
val conf = new SparkConf().setMaster("local[*]").set("spark.cassandra.connection.host", "localhost")
val sc = new SparkContext(conf)
val collection = sc.parallelize(Seq(("word1", 30), ("word2", 40)))
collection.saveToCassandra("test", "words", SomeColumns("word", "count"))
sbt 程序集编译时没有任何问题，但在提交应用程序时出现此错误：
