为 Spark 创建 JAR

Question

我正在关注这个 guide，但是当我尝试使用 sbt.

我有 simple.sbt 作为：

name := "Simple Project"
version := "1.0"
scalaVersion := "2.10.4"
libraryDependencies += "org.apache.spark" % "spark-core_2.10" % "1.6.0"

这是错误：

sbt package
[INFO]  ..
[warn]  [NOT FOUND  ] org.eclipse.jetty.orbit#javax.servlet;3.0.0.v201112011016!javax.servlet.orbit (255ms)

Scala 版本，但我在某处读到它无关紧要：

gsamaras@gsamaras:~/spark-1.6.0-bin-hadoop2.6/code$ scala -version
Scala code runner version 2.11.6 -- Copyright 2002-2013, LAMP/EPFL

和 sbt 版本：

gsamaras@gsamaras:~/spark-1.6.0-bin-hadoop2.6/code$ sbt sbt-version
[info] Set current project to Simple Project (in build file:/home/gsamaras/spark-1.6.0-bin-hadoop2.6/code/)
[info] 0.11.3

相关：SBT, Jetty and Servlet 3.0

Answer 1

将 sbt 更新到最新版本，方法是（某些步骤可能是可选的）：

sudo apt-get remove sbt
echo "deb https://dl.bintray.com/sbt/debian /" | sudo tee -a /etc/apt/sources.list.d/sbt.list
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv 642AC823
sudo apt-get update
sudo apt-get install sbt
sudo apt-get upgrade sbt

你会没事的。
