Subject java.lang.ClassNotFoundException on driver class in executor
Date Sun, 21 Sep 2014 19:52:53 GMT
Hi,

I am running spark from my IDE (InteliJ) using YARN as my cluster manager. However, the executor
node is not able to find my main driver class “LascoScript”. I keep getting  java.lang.ClassNotFoundException.
I tried adding  the jar of the main class by running the snippet below


   val conf = new SparkConf().set("spark.driver.host", "barrymac")
                              .setMaster("yarn-client")
                              .setAppName("Lasco Script”)
			      .setJars(SparkContext.jarOfClass(this.getClass).toSeq)

But the jarOfClass function returns nothing. See below for logs.
