Question

我正在使用Scala 2.11.8并使用maven在IntelliJ

中构建jar文件

我在mobaxterm中运行我的程序：

/opt/spark-1.6.1-bin-hadoop2.6/bin/spark-submit --class CDR.SQL cdr-maven-1.0-SNAPSHOT.jar

这是错误消息：

线程中的异常＆＃34; main＆＃34; java.lang.NoSuchMethodError：scala.reflect.api.JavaUniverse.runtimeMirror（Ljava / lang / ClassLoader;）Lscala / reflect / api / JavaUniverse $ JavaMirror; 在CDR.SQL $。（SQL.scala：24）在CDR.SQL $。（SQL.scala）在CDR.SQL.main（SQL.scala） at sun.reflect.NativeMethodAccessorImpl.invoke0（Native Method） at sun.reflect.NativeMethodAccessorImpl.invoke（NativeMethodAccessorImpl.java:62） at sun.reflect.DelegatingMethodAccessorImpl.invoke（DelegatingMethodAccessorImpl.java:43） at java.lang.reflect.Method.invoke（Method.java:498）在org.apache.spark.deploy.SparkSubmit $ .org $ apache $ spark $ deploy $ SparkSubmit $$ runMain（SparkSubmit.scala：731）在org.apache.spark.deploy.SparkSubmit $ .doRunMain $ 1（SparkSubmit.scala：181）在org.apache.spark.deploy.SparkSubmit $ .submit（SparkSubmit.scala：206）在org.apache.spark.deploy.SparkSubmit $ .main（SparkSubmit.scala：121）在org.apache.spark.deploy.SparkSubmit.main（SparkSubmit.scala）

这是我的pom.xml文件：

我该如何解决这个问题？

感谢您的帮助！

Answer 1

您是否已下载Spark发行版或自行构建？

Spark 1.6默认使用Scala 2.10构建。请将您的Scala版本更改为2.10或将Spark更新为2.0，默认情况下使用Scala 2.11

构建

Answer 2

检查版本。

<build>
    <plugins>
        <plugin>
            <groupId>org.scala-tools</groupId>
            <artifactId>maven-scala-plugin</artifactId>
            <version>2.15.2</version>
            <executions>
                <execution>

看起来您使用的是2.15.x版本。
