Hello
I wrote this simple job in scala:
$ cat Myjob.scala
import org.apache.spark.sql.SparkSession
object Myjob {
def main(args: Array[String]): Unit = {
val sparkSession = SparkSession.builder.appName("Simple
Application").getOrCreate()
val sparkContext = sparkSession.sparkContext
val arrayRDD = sparkContext.parallelize(List(1,2,3,4,5,6,7,8))
println(arrayRDD.getClass, arrayRDD.count())
}
}
After package it then I submit it to spark, it gets the error:
$ /opt/spark/bin/spark-submit --class "Myjob" --master local[4]
target/scala-2.13/my-job_2.13-1.0.jar
Exception in thread "main" java.lang.NoSuchMethodError:

What's the issue?
Thank you.
