Hi all, I encounter an error at spark 1.4.0, and I make an error example as following. Both of the code can run OK on spark-shell, but the second code encounter an error using spark-submit. The only different is that the second code uses a literal function in the map(). but the first code uses a defined function in the map().
Could anyone tell me why this error happen? Thanks ======================the ok code ================= val sparkConf = new SparkConf().setAppName("Mode Example") val sc = new SparkContext(sparkConf) val hive = new HiveContext(sc) val rdd = sc.parallelize(Range(0,1000)) def fff = (input: Int)=>input+1 val cnt = rdd.map(i => Array(1,2,3)).map(arr => { arr.map(fff) }).count() print(cnt) ==============not ok code ============ val sparkConf = new SparkConf().setAppName("Mode Example") val sc = new SparkContext(sparkConf) val hive = new HiveContext(sc) val rdd = sc.parallelize(Range(0,1000)) //def fff = (input: Int)=>input+1 val cnt = rdd.map(i => Array(1,2,3)).map(arr => { arr.map(_+1) }).count() print(cnt) Submit command: spark-submit --class com.yhd.ycache.magic.Model --jars ./SSExample-0.0.2-SNAPSHOT-jar-with-dependencies.jar --master local ./SSExample-0.0.2-SNAPSHOT-jar-with-dependencies.jar the error info: Exception in thread "main" java.lang.ClassNotFoundException: com.yhd.ycache.magic.Model$$anonfun$10$$anonfun$apply$1 at java.net.URLClassLoader$1.run(URLClassLoader.java:366) at java.net.URLClassLoader$1.run(URLClassLoader.java:355) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(URLClassLoader.java:354) at java.lang.ClassLoader.loadClass(ClassLoader.java:425) at sun.misc.Launcher$AppClassLoader.loadClass(Launcher.java:308) at java.lang.ClassLoader.loadClass(ClassLoader.java:358) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:270) at org.apache.spark.util.InnerClosureFinder$$anon$4.visitMethodInsn(ClosureCleaner.scala:455) at com.esotericsoftware.reflectasm.shaded.org.objectweb.asm.ClassReader.accept(Unknown Source) at com.esotericsoftware.reflectasm.shaded.org.objectweb.asm.ClassReader.accept(Unknown Source) at org.apache.spark.util.ClosureCleaner$.getInnerClosureClasses(ClosureCleaner.scala:101) at org.apache.spark.util.ClosureCleaner$.org$apache$spark$util$ClosureCleaner$$clean(ClosureCleaner.scala:197) at org.apache.spark.util.ClosureCleaner$.clean(ClosureCleaner.scala:132) at org.apache.spark.SparkContext.clean(SparkContext.scala:1891) at org.apache.spark.rdd.RDD$$anonfun$map$1.apply(RDD.scala:294) at org.apache.spark.rdd.RDD$$anonfun$map$1.apply(RDD.scala:293) at org.apache.spark.rdd.RDDOperationScope$.withScope(RDDOperationScope.scala:148) at org.apache.spark.rdd.RDDOperationScope$.withScope(RDDOperationScope.scala:109) at org.apache.spark.rdd.RDD.withScope(RDD.scala:286) at org.apache.spark.rdd.RDD.map(RDD.scala:293) at com.yhd.ycache.magic.Model$.main(SSExample.scala:238) at com.yhd.ycache.magic.Model.main(SSExample.scala) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.apache.spark.deploy.SparkSubmit$.org$apache$spark$deploy$SparkSubmit$$runMain(SparkSubmit.scala:664) at org.apache.spark.deploy.SparkSubmit$.doRunMain$1(SparkSubmit.scala:169) at org.apache.spark.deploy.SparkSubmit$.submit(SparkSubmit.scala:192) at org.apache.spark.deploy.SparkSubmit$.main(SparkSubmit.scala:111) at org.apache.spark.deploy.SparkSubmit.main(SparkSubmit.scala)
