我正在关注这个site 来安装 Jupyter Notebook、PySpark 并集成两者。

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。

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

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

我打开kernel.json并写下以下内容：

{
 "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。

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

MacBook:~ Agus$ jupyter console --kernel pyspark

【解决方案1】：

将 pyspark 与 jupyter notebook 集成的多种方式。
1.安装Apache Toree。

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

你可以通过

检查安装

 jupyter kernelspec list

您将获得 toree pyspark 内核的条目

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

之后，如果您愿意，可以安装其他解释器，如 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"

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

仅将pyspark 安装为python package
pip install pyspark

现在您可以像导入另一个 python 包一样导入 pyspark。

【解决方案2】：

最简单的方法是使用 findspark。首先创建一个环境变量：

export SPARK_HOME="{full path to Spark}"

然后安装 findspark：

pip install findspark

然后启动 jupyter notebook 并且以下应该可以工作：

import findspark
findspark.init()

import pyspark
