Ошибка Spark com.fasterxml.jackson.module

Это немного странно. При запуске очень простой sparkContext.parallelize(List("1","2","3"))

Я получаю следующую ошибку:

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;

Я предполагаю, что в зависимостях некоторых библиотек есть конфликт. Мой файл build.sbt выглядит так:

scalaVersion := "2.11.7"

Любые указатели на то, где искать?

Спасибо

Spring Boot 1.3.1 + Проблема Apache Spark 1.6.0 была решена путем добавления зависимости:

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

Нет исключений из любой другой зависимости, требуемой.

По сути, это был конфликт зависимости из-за json-play и искры с использованием разных версий привязки данных Jackson. Этот build.sbt, похоже, решает проблему:

Просто добавьте эти строки в свой SBT.

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

Ответ 4

у вас могут возникнуть проблемы с использованием Spring Boot и Spark в тех же проектах. На всякий случай - исключить зависимости Jackson-databind от других проектов, кроме Spark.

Ответ 5

У меня также была такая же проблема, и решение njjnex работало для меня! Я использовал Spring Boot 1.3.3 + Spark 1.6.1 и Gradle 2.9 как инструмент построения. Вот решение для пользователей Gradle:

 compile group: 'com.fasterxml.jackson.core', name: 'jackson-databind', version: '2.4.4'

Если вы испытываете проблемы, всегда можете попробовать другую версию, которую вы можете найти здесь (применимо к пользователям Maven и SBT)
