Spark 本地模式
本地模式极大简化了我们的测试步骤
其实很简单，如下：
package wordcount
import org.apache.spark.{SparkConf, SparkContext}
object ForeachDemo {
def main(args: Array[String]): Unit = {
/*local[2]表示启动本地二个进程，local一个进程*/
val conf=new SparkConf().setAppName("ForeachDemo").setMaster("local")
val sc=new SparkContext(conf)
val rdd=sc.parallelize(List(1,2,3,4,5,6,7,8,9),3)
rdd.foreach(println(_))
sc.stop()
}
}
