为什么提交作业失败，＆QUOT;的NoSuchMethodError：scala.runtime.VolatileObjectRef.zero（）Lscala /运行/ VolatileObjectRef;＆QUOT;？ [英] Why does submitting a job fail with "NoSuchMethodError: scala.runtime.VolatileObjectRef.zero()Lscala/runtime/VolatileObjectRef;"?

问题描述

我想提出一个火花的工作

I'm trying to submit a spark job

它开始是这样的：

import javax.xml.parsers.{SAXParser, SAXParserFactory}

import org.apache.spark
import org.apache.spark.graphx.{Graph, Edge, VertexId}
import org.apache.spark.rdd.{PairRDDFunctions, RDD}
import org.apache.spark.storage.StorageLevel
import org.apache.spark.{SparkContext, SparkConf}
import scala.util.Try
import org.apache.log4j.{Level, Logger}


object MyApp {

  def main(args: Array[String]) {

    val sparkConf = new SparkConf().setAppName("MyApp")
    val sc = new SparkContext(sparkConf)

当我启动它，我得到以下错误：

And when I launch it I get the following error:

App > Exception in thread "main" java.lang.NoSuchMethodError: scala.runtime.VolatileObjectRef.zero()Lscala/runtime/VolatileObjectRef;
App > at MyApp$.main(MyApp.scala)
App > at MyApp.main(MyApp.scala)
App > at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
App > at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57)

App > at org.apache.spark.deploy.SparkSubmit$.main(SparkSubmit.scala:75)
App > at org.apache.spark.deploy.SparkSubmit.main(SparkSubmit.scala)

我是什么做错了吗？

What am I doing wrong?

编辑：包括完整的堆栈跟踪。
使用Scala 2.10和Spark 1.2.0。
什么是奇怪的是，在我的罐子，我有两个班。当我提出火花之一，它的工作原理（这是一个4行假人的工作），但是当我运行较长的（约40行），如果失败，出现错误上述

Included full stack trace. Using Scala 2.10 and Spark 1.2.0. What's weird is that in my jar, I have two classes. When I spark submit one, it works (it's a 4 lines dummy job), but when I run the longer one (about 40 lines), if fails with the error above

推荐答案

零（）在 scala.runtime.VolatileObjectRef 已在斯卡拉2.11被引入
你可能有一个库编译反对斯卡拉2.11和Scala的2.10运行时中运行。

zero() on scala.runtime.VolatileObjectRef has been introduced in Scala 2.11 You probably have a library compiled against Scala 2.11 and running on a Scala 2.10 runtime.

请参阅

• 2.10：的https://github.com/scala/scala/blob/2.10.x/src/library/scala/runtime/VolatileObjectRef.java


• V2.11：的https://github.com/scala/scala/blob/2.11.x/src/library/scala/runtime/VolatileObjectRef.java
