Spark com.fasterxml.jackson.module错误

Question

这有点奇怪.当运行非常简单sparkContext.parallelize(List("1","2","3"))

我收到以下错误:

java.lang.VerifyError: class com.fasterxml.jackson.module.scala.ser.ScalaIteratorSerializer overrides final method withResolved.(Lcom/fasterxml/jackson/databind/BeanProperty;Lcom/fasterxml/jackson/databind/jsontype/TypeSerializer;Lcom/fasterxml/jackson/databind/JsonSerializer;)Lcom/fasterxml/jackson/databind/ser/std/AsArraySerializerBase;

我猜一些库的依赖性存在一些冲突.我的build.sbt看起来像这样:

scalaVersion := "2.11.7"

  Resolver.mavenLocal,
  "Scala-Tools Maven2 Repository" at "http://scala-tools.org/repo-releases",

).map(
  _.excludeAll(ExclusionRule(organization = "org.mortbay.jetty"))
)

test in assembly := {}

任何关于在哪里寻找的指针？

谢谢

Answer 1

通过添加依赖项解决了Spring Boot 1.3.1 + Apache Spark 1.6.0问题:

    <dependency>
        <groupId>com.fasterxml.jackson.core</groupId>
        <artifactId>jackson-databind</artifactId>
        <version>2.4.4</version>
   </dependency>

不排除任何其他依赖性要求.

Answer 2

实际上,由于使用不同版本的jackson data-bind的json-play和spark,这是一个依赖性冲突.这build.sbt似乎解决了这个问题:

Answer 3

只需在SBT中添加这些行即可.

dependencyOverrides ++= Set(
  "com.fasterxml.jackson.core" % "jackson-databind" % "2.4.4"
)
