我是Apache Spark的新手，并尝试在我的本地spark设置上运行示例Pi Calculation应用程序（使用独立群集）。 Master，Slave和Driver都在我的本地机器上运行。
我注意到的是，PI已成功计算，但在从属日志中，我看到使用exitStatus 1杀死了Worker / Executor。 我没有看到任何错误/异常记录到控制台。 我尝试在类似问题上寻求帮助，但大多数搜索命中都指的是exitStatus 137等（例如：Spark application kills executor）
我惨遭失败，理解为什么工人被杀，而不是用＆＃39; EXITED＆＃39;州。我认为这与我如何执行应用程序有关，但我不太清楚我做错了什么。
有人可以指导我确定根本原因吗？
下面给出了我用于PI计算的代码以及主，从，驱动程序的日志。
PI计算应用
package sparky
import org.apache.spark.scheduler._
import org.apache.spark.sql.SparkSession
import scala.math.random
object Application {
def runSpark(args: Array[String] ): Unit = {
val spark = SparkSession
.builder
.appName("Spark Pi")
.getOrCreate()
spark.sparkContext.addSparkListener(new MyListener())
val slices = if (args.length > 0) args(0).toInt else 2
val n = math.min(100000L * slices, Int.MaxValue).toInt // avoid overflow
val count = spark.sparkContext.parallelize(1 until n, slices).map { i =>
val x = random * 2 - 1
val y = random * 2 - 1
if (x * x + y * y <= 1) 1 else 0
}.reduce(_ + _)
println("Pi is roughly " + 4.0 * count / (n - 1))
spark.stop()
}
def main(args: Array[String]) = {
Application.runSpark(args)
}
}
