I am new to Apache Spark and was trying to run the example Pi Calculation application on my local spark setup (using Standalone Cluster). Both the Master, Slave and Driver are running on my local machine.
What I am noticing is that, the PI is calculated successfully, however in the slave logs I see that the Worker/Executor is being killed with exitStatus 1. I do not see any errors/exceptions logged to the console otherwise. I tried finding help on similar issue, but most of the search hits were referring to exitStatus 137 etc. (e.g: Spark application kills executor)
I have failed miserably to understand why the Worker is being killed instead of completing the execution with 'EXITED' state. I think it's related to how I am executing the app, but am not quite clear what am I doing wrong.
Can someone guide me on identifying the root cause?
Given below is the code I am using for PI calculation and the logs of the master, slave, driver respsectively.
PI Calculation Application
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)
}
}
