Spark在windows上默认使用IPython编辑器

在%SPARK_HOME%\bin目录下，有pyspark，pyspark.cmd，pyspark2.cmd文件。

其中pyspark是linux操作系统或Mac当中使用。

pyspark.cmd和pyspark2.cmd是windows操作系统中使用。

其中pyspark.cmd文件如下：

@echo off

rem This is the entry point for running PySpark. To avoid polluting the
rem environment, it just launches a new cmd to do the real work.

cmd /V /E /C ""%~dp0pyspark2.cmd" %*"

实际上执行的是pyspark2.cmd文件。

那么我们看下pyspark2.cmd文件内容：

@echo off

rem Figure out where the Spark framework is installed
call "%~dp0find-spark-home.cmd"

call "%SPARK_HOME%\bin\load-spark-env.cmd"
set _SPARK_CMD_USAGE=Usage: bin\pyspark.cmd [options]

rem Figure out which Python to use.
if "x%PYSPARK_DRIVER_PYTHON%"=="x" (
  set PYSPARK_DRIVER_PYTHON=python
  if not [%PYSPARK_PYTHON%] == [] set PYSPARK_DRIVER_PYTHON=%PYSPARK_PYTHON%
)

set PYTHONPATH=%SPARK_HOME%\python;%PYTHONPATH%
set PYTHONPATH=%SPARK_HOME%\python\lib\py4j-0.10.6-src.zip;%PYTHONPATH%

set OLD_PYTHONSTARTUP=%PYTHONSTARTUP%
set PYTHONSTARTUP=%SPARK_HOME%\python\pyspark\shell.py

call "%SPARK_HOME%\bin\spark-submit2.cmd" pyspark-shell-main --name "PySparkShell" %*

我们可以看到：set PYSPARK_DRIVER_PYTHON=python将python设置给driver驱动。

我们想使用IPython编辑器，我们将值改为ipython就行。

set PYSPARK_DRIVER_PYTHON=ipython

设置好后，重新使用pyspark打开的dos窗口，就是IPython编辑器了。
