我得到這個錯誤每次我運行我的Scala程序火花與卡桑德拉連接器火花工作卡桑德拉錯誤

at com.datastax.spark.connector.rdd.CassandraTableScanRDD.createStatement(CassandraTableScanRDD.scala:163)
這裏是我的程序
/** CassandraJob.scala **/
import com.datastax.spark.connector._
import org.apache.spark._
object CassandraJob {
def main(args: Array[String]) {
val conf = new SparkConf(true)
.set("spark.cassandra.connection.host", "172.28.0.164")
.set("soark.cassandra.connection.rpc.port", "9160")
val sc = new SparkContext(conf)
val rdd = sc.cassandraTable("eventtest", "simpletbl");
println("cassandra row count : " + rdd.count + ", cassanra row : " + rdd.first)
}
}
我使用SBT編譯生成文件時，sbt包
這裏是我如何提交點火作業
