End of File Exception in Spark cluster - docker

Question

I created docker containers for Spark Standalone mode. Like in this article:
https://dev.to/mvillarrealb/creating-a-spark-standalone-cluster-with-docker-and-docker-compose-2021-update-6l4
As a driver, I make a simple spark job with calculation and try to start it in cluster mode.
val handle = new SparkLauncher()
.setMaster("spark://spark-master:7077")
.setAppName("MyDriver")
.setVerbose(true)
.setAppResource(s"hdfs://spark-master:7077/opt/spark-apps/sparkcluster_2.12-0.1.0-SNAPSHOT.jar")
.setMainClass(DriverTest.getClass.getName)
.setDeployMode("cluster")
.startApplication()
import org.apache.spark.launcher.SparkAppHandle
while (!handle.getState.equals(SparkAppHandle.State.FINISHED)) {
println("App State: " + handle.getState)
Thread.sleep(1000)
}
Could you please tell me, what URL needs set to "setAppResource" from the machine where I run SparkLaunch, from master node or HDFS path?
If I used path "hdfs://spark-master:7077/opt/spark-apps/sparkcluster_2.12-0.1.0-SNAPSHOT.jar" where spark-master:7077 master node, /opt/spark-apps/sparkcluster_2.12-0.1.0-SNAPSHOT.jar path on master node, I will get this exception.

Also I see, that my master node lost worker nodes in execution time. After kill process Master see workers.
