一.环境介绍：

1.安装jdk 7以上

2.python 2.7.11

3.IDE pycharm

4.package: spark-1.6.0-bin-hadoop2.6.tar.gz

二.Setup

1.解压spark-1.6.0-bin-hadoop2.6.tar.gz 到目录D:\spark-1.6.0-bin-hadoop2.6

2.配置环境变量Path，添加D:\spark-1.6.0-bin-hadoop2.6\bin,此后可以在cmd端输入pySpark,返回如下则安装完成：

3.将D:\spark-1.6.0-bin-hadoop2.6\python下的pySpark文件拷贝到C:\Python27\Lib\site-packages

4.安装py4j ， pip install py4j -i https://pypi.douban.com/simple

5.配置pychar环境变量：

三.Example

1.make a new python file: wordCount.py 

#!/usr/bin/env python
# -*- coding: utf-8 -*-
import sys
from pyspark import SparkContext
from operator import add
import  re

def main():
    sc = SparkContext(appName= "wordsCount")
    lines = sc.textFile(‘words.txt‘)
    counts = lines.flatMap(lambda  x: x.split(‘ ‘))                .map( lambda  x : (x, 1))                .reduceByKey(add)
    output = counts.collect()
    print output
    for (word, count) in output:
        print "%s: %i" %(word, count)

    sc.stop()

if __name__ =="__main__":
    main()

2.代码中的words.txt如下：

The dynamic lifestyle
people lead nowadays
causes many reactions
 in our bodies and
 the one that is the
 most frequent of all
 is the headache

3.配置pycharm环境变量：

 3.1 工具栏 run --> Edit configuration-->点击箭头位置 

  3.2  然后点击 + ，输入key：SPARK_HOME， value： D:\spark-1.6.0-bin-hadoop2.6

4.输出结果如下图：

四.深入练习：

1.文档：http://spark.apache.org/docs/latest/api/python/pyspark.html

2.在解压的Spark文档下，有example下有很多实例可以练习。D:\spark-1.6.0-bin-hadoop2.6\examples\src\main\python
