Exception in thread "main" java.lang.NoClassDefFoundError while running Spark program using spark-submit

Question

I have written a following Spark program in Scala. I exported it as JAR file. When I run it in Cloudera Spark cluster using spark-submit command, it is giving me Class Not found error.

import org.apache.spark.SparkConf
import org.apache.spark.sql.SaveMode
import org.apache.spark.sql.SparkSession


object AirflowFileReader extends App {
  
  val sparkConf = new SparkConf()
  sparkConf.set("spark.app.name" , "load and filter a csv file")
  sparkConf.set("spark.master" , "local[2]")
  
  val spark = SparkSession.builder()
  .config(sparkConf)
  .getOrCreate()
  
  val ordersDf = spark.read
                .format("csv")
                .option("header", true)
                .option("inferSchema", true)
                .option("path", "airflow_input_nw/orders.csv") 
                .load();

  val ordersDf1=spark.sql("select * from orders where order_status='CLOSED'")
  
  ordersDf1.write.format("csv").mode(SaveMode.Overwrite).option("path","airflow_output").save()

  
  
}

Command to execute in Cloudera Quickstart terminal -

spark-submit --class AirflowFileReader /home/cloudera/sparkpractice.jar

Error -

[root@quickstart cloudera]# spark-submit --class AirflowFileReader
