scala console error: object apache is not a member of package org
提问by Timothée HENRY
I am trying the code proposed here: http://spark.apache.org/docs/1.2.1/mllib-ensembles.html#classification
我正在尝试这里提出的代码：http: //spark.apache.org/docs/1.2.1/mllib-ensemble.html#classification
using the Scala console (Scala version = Scala code runner version 2.10.4), and get the following error:
使用 Scala 控制台（Scala 版本 = Scala 代码运行器版本 2.10.4），并得到以下错误：
scala> import org.apache.spark.mllib.tree.RandomForest
<console>:8: error: object apache is not a member of package org
import org.apache.spark.mllib.tree.RandomForest
^
I then followed the advice from hereand tried to build a simple self-contained application, but ran into a different problem:
然后我按照这里的建议尝试构建一个简单的自包含应用程序，但遇到了一个不同的问题：

Can anyone advise what I could try?

You can find detailed steps in this posthow to write self contained Spark application using SBT in Scala. In sbt configuration file you should specify the dependent libraries.
您可以在这篇文章中找到详细步骤如何在 Scala 中使用 SBT 编写自包含的 Spark 应用程序。在 sbt 配置文件中，您应该指定依赖库。
libraryDependencies ++= Seq("org.apache.spark" % "spark-core_2.10" % "1.2.1",
"org.apache.spark" % "spark-mllib_2.10" % "1.2.1")
Then compile using following command
然后使用以下命令编译
sbt package
