我正在尝试使用Spark 1.1.0和Jackson 2.4.4运行spark-submit。我有scala代码，它使用Jackson将JSON反序列化为case类。这本身就可以正常工作，但是当我将它与spark一起使用时，我会收到以下错误：

I am trying to run spark-submit with Spark 1.1.0 and Jackson 2.4.4. I have scala code which uses Jackson to de-serialize JSON into case classes. That works just fine on its own, but when I use it with spark I get the following error:

15/05/01 17:50:11 ERROR Executor: Exception in task 0.0 in stage 1.0 (TID 2) java.lang.NoSuchMethodError: com.fasterxml.jackson.databind.introspect.POJOPropertyBuilder.addField(Lcom/fasterxml/jackson/databind/introspect/AnnotatedField;Lcom/fasterxml/jackson/databind/PropertyName;ZZZ)V at com.fasterxml.jackson.module.scala.introspect.ScalaPropertiesCollector$fasterxml$jackson$module$scala$introspect$ScalaPropertiesCollector$$_addField(ScalaPropertiesCollector.scala:109) at com.fasterxml.jackson.module.scala.introspect.ScalaPropertiesCollector$$anonfun$_addFields$2$$anonfun$apply$11.apply(ScalaPropertiesCollector.scala:100) at com.fasterxml.jackson.module.scala.introspect.ScalaPropertiesCollector$$anonfun$_addFields$2$$anonfun$apply$11.apply(ScalaPropertiesCollector.scala:99) at scala.Option.foreach(Option.scala:236) at com.fasterxml.jackson.module.scala.introspect.ScalaPropertiesCollector$$anonfun$_addFields$2.apply(ScalaPropertiesCollector.scala:99) at com.fasterxml.jackson.module.scala.introspect.ScalaPropertiesCollector$$anonfun$_addFields$2.apply(ScalaPropertiesCollector.scala:93) at scala.collection.GenTraversableViewLike$Filtered$$anonfun$foreach$4.apply(GenTraversableViewLike.scala:109) at scala.collection.Iterator$class.foreach(Iterator.scala:727) at scala.collection.AbstractIterator.foreach(Iterator.scala:1157) at scala.collection.IterableLike$class.foreach(IterableLike.scala:72) at scala.collection.SeqLike$$anon$2.foreach(SeqLike.scala:635) at scala.collection.GenTraversableViewLike$Filtered$class.foreach(GenTraversableViewLike.scala:108) at scala.collection.SeqViewLike$$anon$5.foreach(SeqViewLike.scala:80) at com.fasterxml.jackson.module.scala.introspect.ScalaPropertiesCollector._addFields(ScalaPropertiesCollector.scala:93)

这是我的build.sbt：

Here is my build.sbt:

//scalaVersion in ThisBuild := "2.11.4" scalaVersion in ThisBuild := "2.10.5" retrieveManaged := true libraryDependencies += "org.scala-lang" % "scala-reflect" % scalaVersion.value libraryDependencies ++= Seq( "junit" % "junit" % "4.12" % "test", "org.scalatest" %% "scalatest" % "2.2.4" % "test", "org.mockito" % "mockito-core" % "1.9.5", "org.specs2" %% "specs2" % "2.1.1" % "test", "org.scalatest" %% "scalatest" % "2.2.4" % "test" ) libraryDependencies ++= Seq( "org.apache.hadoop" % "hadoop-core" % "0.20.2", "org.apache.hbase" % "hbase" % "0.94.6" ) //libraryDependencies += "org.apache.spark" % "spark-core_2.10" % "1.3.0" libraryDependencies += "org.apache.spark" % "spark-core_2.10" % "1.1.0" libraryDependencies += "com.fasterxml.jackson.module" %% "jackson-module-scala" % "2.4.4" //libraryDependencies += "com.fasterxml.jackson.module" %% "jackson-module-scala" % "2.3.1" //libraryDependencies += "com.fasterxml.jackson.module" %% "jackson-module-scala" % "2.5.0" libraryDependencies += "com.typesafe" % "config" % "1.2.1" resolvers += Resolver.mavenLocal

尽可能看，我尝试了许多不同版本的杰克逊。

As you can see, I have tried many different versions of Jackson.

这是我用来运行spark提交的shell脚本：

Here is the shell script I use to run spark submit:

#!/bin/bash sbt package CLASS=com.test.spark.test.SparkTest SPARKDIR=/Users/user/Desktop/ #SPARKVERSION=1.3.0 SPARKVERSION=1.1.0 SPARK="$SPARKDIR/spark-$SPARKVERSION/bin/spark-submit" jar_jackson=/Users/user/scala_projects/lib_managed/bundles/com.fasterxml.jackson.module/jackson-module-scala_2.10/jackson-module-scala_2.10-2.4.4.jar "$SPARK" \ --class "$CLASS" \ --jars $jar_jackson \ --master local[4] \ /Users/user/scala_projects/target/scala-2.10/spark_project_2.10-0.1-SNAPSHOT.jar \ print /Users/user/test.json

我使用 - jars 到jackson jar的路径到spark-submit命令。我甚至尝试过不同版本的Spark。我甚至还指定了Jackson jars数据绑定，注释等的路径，但这并没有解决问题。任何帮助，将不胜感激。谢谢

I use --jars to the path of the jackson jar to the spark-submit command. I have even tried different versions of Spark. I have also even specified the paths for the Jackson jars databind, annotations, etc but that didn't resolve the issue. Any help would be appreciated. Thank you

推荐答案

我遇到了同样的问题，我的play-json jar使用的是jackson 2.3.2而spark正在使用jackson 2.4 .4。 当我运行spark应用程序时，它无法在jackson-2.3.2中找到该方法而且我得到了相同的异常。

I had the same problem where my play-json jar was using jackson 2.3.2 and spark was using jackson 2.4.4. While I was running the spark application, it was unable to find the method in jackson-2.3.2 and I got the same exception.

我检查了杰克逊的maven依赖层次结构。它显示了它所使用的版本以及哪个jar（这里播放使用2.3.2）和我的play-json首先放在依赖列表中，它花了2.3.2版本。

I checked the maven dependency hierarchy for jackson. It displayed the version it took and which jar (Here play used 2.3.2) and as my play-json placed at first in dependency list, it took 2.3.2 version.

所以我尝试将游戏依赖项放在所有依赖项/火花依赖项之后，它运行得很好。这次耗时2.4.4，版本2.3.2被省略。

So I tried placing the play dependency at the end of the all dependencies/after the spark dependency and it worked pretty well. It took 2.4.4 this time and version 2.3.2 is omitted.

请注意，如果两个依赖版本是在依赖树中的相同深度，直到Maven 2.0.8没有定义哪一个会获胜，但是自Maven 2.0.9以来，这是计数的声明中的顺序：第一个声明获胜。

Note that if two dependency versions are at the same depth in the dependency tree, until Maven 2.0.8 it was not defined which one would win, but since Maven 2.0.9 it's the order in the declaration that counts: the first declaration wins.
