How to start a Spark Shell using pyspark in Windows?

问题

I am a beginner in Spark and trying to follow instructions from here on how to initialize Spark shell from Python using cmd: http://spark.apache.org/docs/latest/quick-start.html

But when I run in cmd the following:

C:\Users\Alex\Desktop\spark-1.4.1-bin-hadoop2.4\>c:\Python27\python bin\pyspark

then I receive the following error message:

File "bin\pyspark", line 21 
export SPARK_HOME="$(cd ="$(cd "`dirname "$0"`"/..; pwd)" 
SyntaxError: invalid syntax

What am I doing wrong here?

P.S. When in cmd I try just C:\Users\Alex\Desktop\spark-1.4.1-bin-hadoop2.4>bin\pyspark

then I receive ""python" is not recognized as internal or external command, operable program or batch file".

You need to have Python available in the system path, you can add it with setx:

setx path "%path%;C:\Python27"

I'm a fairly new Spark user (as of today, really). I am using spark 1.6.0 on Windows 10 and 7 machines. The following worked for me:

import os

import sys

spark_home = os.environ.get('SPARK_HOME', None)

if not spark_home:

raise ValueError('SPARK_HOME environment variable is not set')

sys.path.insert(0, os.path.join(spark_home, 'python'))

sys.path.insert(0, os.path.join(spark_home, 'C:/spark-1.6.0-bin-hadoop2.6/python/lib/py4j-0.9-src.zip'))

execfile(os.path.join(spark_home, 'python/pyspark/shell.py'))

Using the code above, I was able to launch Spark in an IPython notebook and my Enthought Canopy Python IDE. Before, this, I was only able to launch pyspark through a cmd prompt. The code above will only work if you have your Environment Variables set correctly for Python and Spark (pyspark).

With the reference and help of the user "maxymoo" I was able to find a way to set a PERMANENT path is Windows 7 as well. The instructions are here:

I run these set of path settings whenever I start pyspark in ipython:

import os
import sys
# Sys.setenv('SPARKR_SUBMIT_ARGS'='"--packages" "com.databricks:spark-csv_2.10:1.0.3" "sparkr-shell"') for R
### MANNN restart spart using ipython notebook --profile=pyspark --packages com.databricks:spark-csv_2.10:1.0.3  
os.environ['SPARK_HOME']="G:/Spark/spark-1.5.1-bin-hadoop2.6"

sys.path.append("G:/Spark/spark-1.5.1-bin-hadoop2.6/bin") 
sys.path.append("G:/Spark/spark-1.5.1-bin-hadoop2.6/python") 
sys.path.append("G:/Spark/spark-1.5.1-bin-hadoop2.6/python/pyspark/") 
sys.path.append("G:/Spark/spark-1.5.1-bin-hadoop2.6/python/pyspark/sql")
sys.path.append("G:/Spark/spark-1.5.1-bin-hadoop2.6/python/pyspark/mllib")
sys.path.append("G:/Spark/spark-1.5.1-bin-hadoop2.6/python/lib") 
sys.path.append("G:/Spark/spark-1.5.1-bin-hadoop2.6/python/lib/pyspark.zip")
sys.path.append("G:/Spark/spark-1.5.1-bin-hadoop2.6/python/lib/py4j-0.8.2.1-src.zip") 
sys.path.append("G:/Spark/spark-1.5.1-bin-hadoop2.6/python/lib/pyspark.zip")

from pyspark import SparkContext 
from pyspark import SparkConf
from pyspark import SQLContext 

##sc.stop() # IF you wish to stop the context
sc = SparkContext("local", "Simple App")

Simply set path in System -> Environment Variables -> Path

R Path in my system C:\Program Files\R\R-3.2.3\bin
Python Path in my system c:\python27
Spark Path in my system c:\spark-2

The path must be separated by ";" and there must be no space between paths
