这篇文章主要介绍了Jupyter notebook运行Spark+Scala教程,具有很好的参考价值,希望对大家有所帮助。一起跟随小编过来看看吧
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
