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. -------------------- 14/09/21 10:53:15 WARN TaskSetManager: Lost task 0.0 in stage 0.0 (TID 0, barrymac): java.lang.ClassNotFoundException: LascoScript$$anonfun$1 java.net.URLClassLoader$1.run(URLClassLoader.java:366) java.net.URLClassLoader$1.run(URLClassLoader.java:355) java.security.AccessController.doPrivileged(Native Method) java.net.URLClassLoader.findClass(URLClassLoader.java:354) java.lang.ClassLoader.loadClass(ClassLoader.java:423) java.lang.ClassLoader.loadClass(ClassLoader.java:356) java.lang.Class.forName0(Native Method) java.lang.Class.forName(Class.java:264) org.apache.spark.serializer.JavaDeserializationStream$$anon$1.resolveClass(JavaSerializer.scala:59) java.io.ObjectInputStream.readNonProxyDesc(ObjectInputStream.java:1593) java.io.ObjectInputStream.readClassDesc(ObjectInputStream.java:1514) java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1750) java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1347) java.io.ObjectInputStream.defaultReadFields(ObjectInputStream.java:1964) java.io.ObjectInputStream.readSerialData(ObjectInputStream.java:1888) java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1771) java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1347) java.io.ObjectInputStream.defaultReadFields(ObjectInputStream.java:1964) java.io.ObjectInputStream.readSerialData(ObjectInputStream.java:1888) java.io.ObjectInputStream.readOrdinaryObject(ObjectInputStream.java:1771) java.io.ObjectInputStream.readObject0(ObjectInputStream.java:1347) java.io.ObjectInputStream.readObject(ObjectInputStream.java:369) org.apache.spark.serializer.JavaDeserializationStream.readObject(JavaSerializer.scala:62) org.apache.spark.serializer.JavaSerializerInstance.deserialize(JavaSerializer.scala:87) org.apache.spark.scheduler.ResultTask.runTask(ResultTask.scala:57) org.apache.spark.scheduler.Task.run(Task.scala:54) org.apache.spark.executor.Executor$TaskRunner.run(Executor.scala:177) java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) java.lang.Thread.run(Thread.java:722) 14/09/21 10:53:15 INFO TaskSetManager: Lost task 1.0 in stage 0.0 (TID 1) on executor barrymac: java.lang.ClassNotFoundException (LascoScript$$anonfun$1) [duplicate 1] 14/09/21 10:53:15 INFO TaskSetManager: Starting task 1.1 in stage 0.0 (TID 4, barrymac, NODE_LOCAL, 1312 bytes) 14/09/21 10:53:15 INFO TaskSetManager: Lost task 2.0 in stage 0.0 (TID 2) on executor barrymac: java.lang.ClassNotFoundException (LascoScript$$anonfun$1) [duplicate 2] 14/09/21 10:53:15 INFO TaskSetManager: Starting task 2.1 in stage 0.0 (TID 5, barrymac, NODE_LOCAL, 1312 bytes) 14/09/21 10:53:15 INFO TaskSetManager: Lost task 3.0 in stage 0.0 (TID 3) on executor barrymac: java.lang.ClassNotFoundException (LascoScript$$anonfun$1) [duplicate 3] 14/09/21 10:53:15 INFO TaskSetManager: Starting task 3.1 in stage 0.0 (TID 6, barrymac, NODE_LOCAL, 1312 bytes) 14/09/21 10:53:15 INFO TaskSetManager: Lost task 1.1 in stage 0.0 (TID 4) on executor barrymac: java.lang.ClassNotFoundException (LascoScript$$anonfun$1) [duplicate 4] 14/09/21 10:53:15 INFO TaskSetManager: Starting task 1.2 in stage 0.0 (TID 7, barrymac, NODE_LOCAL, 1312 bytes) 14/09/21 10:53:15 INFO TaskSetManager: Lost task 2.1 in stage 0.0 (TID 5) on executor barrymac: java.lang.ClassNotFoundException (LascoScript$$anonfun$1) [duplicate 5] 14/09/21 10:53:15 INFO TaskSetManager: Starting task 2.2 in stage 0.0 (TID 8, barrymac, NODE_LOCAL, 1312 bytes) 14/09/21 10:53:15 INFO TaskSetManager: Lost task 3.1 in stage 0.0 (TID 6) on executor barrymac: java.lang.ClassNotFoundException (LascoScript$$anonfun$1) [duplicate 6] 14/09/21 10:53:15 INFO TaskSetManager: Starting task 3.2 in stage 0.0 (TID 9, barrymac, NODE_LOCAL, 1312 bytes) 14/09/21 10:53:15 INFO TaskSetManager: Lost task 1.2 in stage 0.0 (TID 7) on executor barrymac: java.lang.ClassNotFoundException (LascoScript$$anonfun$1) [duplicate 7] 14/09/21 10:53:15 INFO TaskSetManager: Starting task 1.3 in stage 0.0 (TID 10, barrymac, NODE_LOCAL, 1312 bytes) 14/09/21 10:53:15 INFO TaskSetManager: Lost task 2.2 in stage 0.0 (TID 8) on executor barrymac: java.lang.ClassNotFoundException (LascoScript$$anonfun$1) [duplicate 8] 14/09/21 10:53:15 INFO TaskSetManager: Starting task 2.3 in stage 0.0 (TID 11, barrymac, NODE_LOCAL, 1312 bytes) 14/09/21 10:53:15 INFO TaskSetManager: Lost task 3.2 in stage 0.0 (TID 9) on executor barrymac: java.lang.ClassNotFoundException (LascoScript$$anonfun$1) [duplicate 9] 14/09/21 10:53:15 INFO TaskSetManager: Starting task 3.3 in stage 0.0 (TID 12, barrymac, NODE_LOCAL, 1312 bytes) 14/09/21 10:53:15 INFO TaskSetManager: Lost task 1.3 in stage 0.0 (TID 10) on executor barrymac: java.lang.ClassNotFoundException (LascoScript$$anonfun$1) [duplicate 10] 14/09/21 10:53:15 ERROR TaskSetManager: Task 1 in stage 0.0 failed 4 times;
