serialization - Spark com.fasterxml.jackson.module 错误

Question

这有点奇怪。运行时很简单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;

我想某些库的依赖项存在一些冲突。我的 build.sbt 看起来像这样:

scalaVersion := "2.11.7"

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

test in assembly := {}

关于在哪里看的任何指示？

谢谢

Answer 1

Spring Boot 1.3.1 + Apache Spark 1.6.0 问题通过添加依赖解决:

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

不排除任何其他所需的依赖项。
