这是我的代码
import org.apache.spark.SparkContext
object WordCount {
def main(args: Array[String]): Unit={
var sc = new SparkContext(“local”,“wordcount”)
var file = sc.textFile("/1np/spark-3.0.0-preview2-bin-hadoop2.7/LICENSE")
file.flatMap(.split(" ")).map((,1)).reduceByKey(+).foreach(println(_))
}
}

这是编译错误
