我是Apache Spark的新手，我试图将一段简单的scala代码部署到Spark。
注意：我正在尝试连接到我通过java参数配置的现有正在运行的群集：spark.master=spark://MyHostName:7077
环境
sbt ：0.13.8
代码
import org.apache.spark.{SparkConf, SparkContext}
object HelloSpark {
def main(args: Array[String]) {
val logFile = "/README.md"
val conf = new SparkConf().setAppName("Simple Application")
val sc = new SparkContext(conf)
val logData = sc.textFile(logFile, 2).cache()
val numAs = logData.filter(line => line.contains("a")).count()
println("%s done!".format(numAs))
}
}
build.sbt
name := "data-streamer210"
version := "1.0"
scalaVersion := "2.10.4"
libraryDependencies ++= Seq(
"org.apache.spark" % "spark-core_2.10" % "1.5.1",

答案 0 :(得分：18)
当您从IntelliJ运行Spark时，您可以连接到“本地”spark JVM或远程群集。
如果您将master设置为本地（例如，setMaster("local[*]")），那么您在本地范围/项目中拥有的任何代码都将可用于您刚刚创建的此临时本地（单个JVM）群集。一切都在本地运行，并在测试结束时退出（如果运行单元测试），或者当您在IntelliJ中作为应用程序运行时退出应用程序。
但是，如果您将master设置为指向远程群集（例如setMaster("spark://localhost:7077")），则需要确保您的群集可以访问您的新代码（在您需要的情况下，它需要有权访问您的关闭）正在传递给filter）。
当我想在正在运行的Spark集群上执行一段新代码时，我通常是通过将我的应用程序打包在Uber Jar中来实现的（参见sbt-assembly）然后将其作为参数传递给{{3 （点击链接查看更多详情）。
答案 1 :(得分：0)
如果您在代码中调用setMaster，即使您将其设置为正确的主控，也会进行有趣的交互。例如，我有这样的代码：
val conf = new SparkConf().setAppName("Simple Application").setMaster("spark://greine:7077")
我提交的内容是这样的：
bin/spark-submit --class SimpleApp --master yarn --deploy-mode cluster /Users/james/Projects/sparkHelloWorld/target/scala-2.11/sparkHelloWorld-assembly-1.0.jar
我相信jar（ sparkHelloWorld-assembly-1.0.jar ）是正确构建的，并且拥有所有必需的类文件。它仍然有一个错误：

一旦我删除了对setMaster("spark://greine:7077")的调用，就会使用相同的spark-submit命令正确运行并完成。
