Jupyter notebook运行Spark+Scala教程

今天在intellij调试spark的时候感觉每次有新的一段代码，都要重新跑一遍，如果用spark-shell，感觉也不是特别方便，如果能像python那样，使用jupyter notebook进行编程就很方便了，同时也适合代码展示，网上查了一下，试了一下，碰到了很多坑，有些是旧的版本，还有些是版本不同导致错误，这里就记录下来安装的过程。

1.运行环境

硬件：Mac

事先装好：Jupyter notebook，spark2.1.0，scala 2.11.8 (这个版本很重要，关系到后面的安装）

2.安装

2.1.scala kernel

从github下载

git clone https://github.com/jupyter-scala/jupyter-scala.git

进入下载的jupyter-scala目录下，运行

bash jupyter-scala

然后查看

jupyter kernelspec list

表示scala已经嵌入到jupyter notebook

2.2.spark kernel

这个也比较好装，但是要注意版本问题，我们用的是toree来装的，首先要安装toree

网上的教程通常直接

pip install toree

但是这个下载的是0.1.0版本，该版本的话问题是，后面装spark kernel后，在jupyter运行spark的时候，默认选的是scala2.10.4版本，会有以下的错误

这个错误太可怕了，就是版本不对，因为spark2.1.0对应的是scala2.11版本的

所以要用下面的方式下载0.2.0版本

pip install https://dist.apache.org/repos/dist/dev/incubator/toree/0.2.0/snapshots/dev1/toree-pip/toree-0.2.0.dev1.tar.gz

后面就可以安装spark kernel了

jupyter toree install --interpreters=Scala --spark_home=/usr/local/Cellar/apache-spark/2.1.0/libexec --user --kernel_name=apache_toree --interpreters=PySpark,SparkR,Scala,SQL

其中spark_home指的是你的spark的安装目录，记住这个安装目录必须到spark中有python之前，比如我的spark中的python（spark中的python文件夹，不是我们自己装的那个）在 /usr/local/Cellar/apache-spark/2.1.0/libexec

查看结果

jupyter kernelspec list

安装成功

3.打开jupyter notebook查看效果

有这么多选项，可以快乐的用jupyter notebook进行spark了
