Hi, I have a 5 nodes yarn cluster, I used spark-submit to submit a simple app.
spark-submit --master yarn target/scala-2.10/simple-project_2.10-1.0.jar --class scala.SimpleApp --num-executors 5 I have set the number of executor to 5, but from sparkui I could see only two executors and it ran very slow. What did I miss ? Thanks, Xiaohe
