Subject number of executors
Date Sat, 16 May 2015 07:01:31 GMT

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 ?
