将PySpark与Jupyter Notebook集成 [英] Integrate PySpark with Jupyter Notebook

问题描述

我正在关注网站以安装Jupyter Notebook，PySpark和整合两者。

I'm following this site to install Jupyter Notebook, PySpark and integrate both.

当我需要创建Jupyter配置文件时，我读到Jupyter配置文件不再存在。所以我继续执行以下几行。

When I needed to create the "Jupyter profile", I read that "Jupyter profiles" not longer exist. So I continue executing the following lines.

$ mkdir -p ~/.ipython/kernels/pyspark

$ touch ~/.ipython/kernels/pyspark/kernel.json

我打开 kernel.json 并写下以下内容：

I opened kernel.json and write the following:

{
 "display_name": "pySpark",
 "language": "python",
 "argv": [
  "/usr/bin/python",
  "-m",
  "IPython.kernel",
  "-f",
  "{connection_file}"
 ],
 "env": {
  "SPARK_HOME": "/usr/local/Cellar/spark-2.0.0-bin-hadoop2.7",
  "PYTHONPATH": "/usr/local/Cellar/spark-2.0.0-bin-hadoop2.7/python:/usr/local/Cellar/spark-2.0.0-bin-hadoop2.7/python/lib/py4j-0.10.1-src.zip",
  "PYTHONSTARTUP": "/usr/local/Cellar/spark-2.0.0-bin-hadoop2.7/python/pyspark/shell.py",
  "PYSPARK_SUBMIT_ARGS": "pyspark-shell"
 }
}

Spark的路径是正确的。

The paths of Spark are correct.

但是，当我运行 jupyter console --ke rnel pyspark 我得到了这个输出：

But then, when I run jupyter console --kernel pyspark I get this output:

MacBook:~ Agus$ jupyter console --kernel pyspark

推荐答案

将pyspark与jupyter笔记本集成的许多方法。< br>
1. 安装 Apache Toree 。

Many ways to integrate pyspark with jupyter notebook.
1.Install Apache Toree.

  pip install jupyter
  pip install toree
  jupyter toree install --spark_home=path/to/your/spark_directory --interpreters=PySpark

您可以通过

 jupyter kernelspec list

你会得到一个条目toree pyspark内核

you will get an entry for toree pyspark kernel

  apache_toree_pyspark    /home/pauli/.local/share/jupyter/kernels/apache_toree_pyspark

之后如果需要，你可以安装其他的解释器，如SparkR，Scala，SQL

Afterwards if you want, you can install other intepreters like SparkR,Scala,SQL

 jupyter toree install --interpreters=Scala,SparkR,SQL

2. 将这些行添加到bashrc

  export SPARK_HOME=/path to /spark-2.2.0
  export PATH="$PATH:$SPARK_HOME/bin"    
  export PYSPARK_DRIVER_PYTHON=jupyter
  export PYSPARK_DRIVER_PYTHON_OPTS="notebook"

在终端输入 pyspark 它将打开一个初始化了sparkcontext的jupyter笔记本。

type pyspark in terminal and it will open a jupyter notebook with sparkcontext initialized.

1. 安装 pyspark 仅作为 python包
   
   pip install pyspark

现在您可以像其他python包一样导入pyspark。

Now you can import pyspark like another python package.
