大数据基础（八）Spark2.0.0下IPython和Notebook的安装配置

环境：

spark 2.0.0,anaconda2

1.spark ipython和notebook安装配置

方法一：

这个方法可以通过网页进入ipython notebook，另开终端可以进入pyspark
如果装有Anaconda 就可以直接如下方式获得IPython界面的登陆，没有装Anaconda的参考最下边的链接自行安装ipython相关包。
vi ~/.bashrc
export PYSPARK_DRIVER_PYTHON=ipython
export PYSPARK_DRIVER_PYTHON_OPTS="notebook --NotebookApp.open_browser=False --NotebookApp.ip='*' --NotebookApp.port=8880"
source ~/.bashrc


重新启动pyspark
出现
ting a Notebook with PySpark
On the driver host, choose a directory notebook_directory to run the Notebook. notebook_directory contains the .ipynb files that represent the different notebooks that can be served.
In notebook_directory, run pyspark with your desired runtime options. You should see output like the following:

方法二：
方法二用ipython可以，但是jupyter有问题，不知道是不是个别的
It is also possible to launch the PySpark shell in IPython, the enhanced Python interpreter. PySpark works with IPython 1.0.0 and later. To use IPython, set the PYSPARK_DRIVER_PYTHON variable to ipython when running bin/pyspark:


$ PYSPARK_DRIVER_PYTHON=ipython ./bin/pyspark
To use the Jupyter notebook (previously known as the IPython notebook),


$ PYSPARK_DRIVER_PYTHON=jupyter ./bin/pyspark
You can customize the ipython or jupyter commands by setting PYSPARK_DRIVER_PYTHON_OPTS.

2. 使用：


Open http://notebook_host:8880/ in a browser.
比如：http://spark01:8880/
New->Python打开Python界面
Shift+Enter or Shift+Return执行命令


注意：

设置IPython后，pyspark就只能用IPython，除非恢复环境变量

3.测试例子

file_in换成你自己的文件，如果是本地就用#那一句，hdfs就默认，修改一下具体地址即可。
