获取异常:java.lang.NoSuchMethodError:scala.reflect.api.JavaUniverse.runtimeMirror(Ljava/lang/ClassLoader;)在使用数据帧时 [英] Getting exception : java.lang.NoSuchMethodError: scala.reflect.api.JavaUniverse.runtimeMirror(Ljava/lang/ClassLoader;) while using data frames

问题描述

在Scala应用程序中使用数据框并使用spark运行它时，出现"java.lang.NoSuchMethodError:scala.reflect.api.JavaUniverse.runtimeMirror(Ljava/lang/ClassLoader;)"错误.但是，如果我仅使用RDD而不使用数据帧，则使用相同的pom和设置不会出现此类错误.另外，在浏览其他帖子时也遇到相同的错误，并提到scala版本必须为2.10，因为spark与2.11 scala不兼容，而我正在使用2.10 scala版本和2.0.0 spark.

I am receiving "java.lang.NoSuchMethodError: scala.reflect.api.JavaUniverse.runtimeMirror(Ljava/lang/ClassLoader;)" error while using dataframes in scala app and running it using spark. However if I work using only RDD's and not dataframes, no such error comes up with same pom and settings. Also while going through other posts with same error, it is mentioned that scala version has to be 2.10 as spark is not compatible with 2.11 scala, and i am using 2.10 scala version with 2.0.0 spark.

Below is the snip from pom:

推荐答案

更改Scala版本

>

<scala.tools.version>2.11</scala.tools.version>

并添加

<dependency>
    <groupId>org.scala-lang</groupId>
    <artifactId>scala-reflect</artifactId>
    <version>${scala.version}</version>
  </dependency>
