线程"main"中的异常java.lang.NoSuchMethodError:scala.Predef $ .refArrayOps([Ljava/lang/Object;)Lscala/collection/mutable/ArrayOps [英] Exception in thread "main" java.lang.NoSuchMethodError: scala.Predef$.refArrayOps([Ljava/lang/Object;)Lscala/collection/mutable/ArrayOps

问题描述

当我在终端中运行时:

sudo spark-submit --master local --class xxx.xxxx.xxx.xxxx.xxxxxxxxxxxxJob --conf 'spark.driver.extraJavaOptions=-Dconfig.resource=xxx.conf' /home/xxxxx/workspace/prueba/pruebas/target/scala-2.11/MiPrueba.jar

我收到以下错误:

内部定义:

version:="0.1"

version := "0.1"

scalaVersion:="2.11.11"

scalaVersion := "2.11.11"

libraryDependencies:

libraryDependencies:

val dependFullList = spark ++ hadoop ++ apisDownload ++ configuration 

配置:

  val configuration = Seq(
    "com.github.pureconfig" %% "pureconfig" % "0.9.2",
    "com.typesafe" % "config" % "1.3.1",
    "org.lz4" % "lz4-java" % "1.4.1"
  )

火花:

  val spark = Seq(
    "org.apache.spark" %% "spark-core" % Versions.spark % "provided" exclude("javax.jms", "jms"),
    "org.apache.spark" %% "spark-sql" % Versions.spark % "provided",
    "com.databricks" %% "spark-xml" % "0.4.1"
    // https://mvnrepository.com/artifact/mrpowers/spark-daria
  )

有什么想法吗?

推荐答案

您正在混合Scala版本. Spark 2.4.2不支持Scala 2.11.切换到Spark 2.4.0或用scala 2.12版本替换您的库.

You're mixing scala versions. Spark 2.4.2 doesn't support scala 2.11. Switch to Spark 2.4.0 or replace your libraries with scala 2.12 versions.

https://spark.apache.org/releases/spark-release-2-4-2.html

请注意，从2.4.1开始不推荐使用Scala 2.11.从2.4.2开始，针对Scala 2.12编译了预构建的便捷二进制文件. Spark仍在Maven Central中针对2.11和2.12交叉发布，并且可以从源代码针对2.11构建.

Note that Scala 2.11 support is deprecated from 2.4.1 onwards. As of 2.4.2, the pre-built convenience binaries are compiled for Scala 2.12. Spark is still cross-published for 2.11 and 2.12 in Maven Central, and can be built for 2.11 from source.
