apache-spark - 将PySpark与Jupyter Notebook集成

我正在按照这个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并编写以下内容：

{
 "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。

但是然后，当我运行jupyter console --kernel pyspark时，得到以下输出：

MacBook:~ Agus$ jupyter console --kernel pyspark
/usr/bin/python: No module named IPython
Traceback (most recent call last):
  File "/usr/local/bin/jupyter-console", line 11, in <module>

    self.init_kernel_info()

    raise RuntimeError("Kernel didn't respond to kernel_info_request")
RuntimeError: Kernel didn't respond to kernel_info_request

最佳答案

将pyspark与jupyter笔记本集成的多种方法。
1.安装Apache Toree。

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

您可以通过以下方式检查安装

 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，如果需要，您可以安装其他解释程序，例如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"

在终端中键入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，您可以像其他python包一样导入pyspark。
