window配置安装pyspark,值得信赖的教程：win10下安装pyspark
，按照教程安装并配置好后，在cmd窗口下输入pyspark即可运行；但是，在pycharm下的黑窗口下输入pyspark，会报错：c:\Windows\System32>pyspark
Java not found and JAVA_HOME environment variable is not set.
Install Java and set JAVA_HOME to point to the Java installation directory.;待解决；
解决方法，增加如下：
import sys
import os
os.environ['SPARK_HOME'] = "E:/1/spark-2.3.0-bin-hadoop2.7/spark-2.3.0-bin-hadoop2.7"
os.environ['HADOOP_HOME'] = "E:/1/hadoop-2.7.1/hadoop-2.7.1"
sys.path.append("C:/Users/tsl/AppData/Local/Programs/Python/Python35/Lib")
sys.path.append("C:/Users/tsl/AppData/Local/Programs/Python/Python35")
下面这样写环境变量也可以：
import sys
import os
os.environ['SPARK_HOME'] = "C:/Users/tsl/AppData/Local/Programs/Python/Python35/Lib/site-packages/pyspark"
os.environ['HADOOP_HOME'] = "E:/1/hadoop-2.7.1/hadoop-2.7.1/bin/winutils/bin"
sys.path.append("C:/Users/tsl/AppData/Local/Programs/Python/Python35/Lib")
sys.path.append("C:/Users/tsl/AppData/Local/Programs/Python/Python35")
pyspark
<module 'pyspark' from 'C:\\Users\\tsl\\AppData\\Local\\Programs\\Python\\Python35\\lib\\site-packages\\pyspark\\__init__.py'>先进入python ,再进入spark,可是这个没有直接进入pyspark有效！（待解决）
注意：.environ[‘SPARK_HOME’] = “E:/1/spark-2.3.0-bin-hadoop2.7/spark-2.3.0-bin-hadoop2.7”，这个路径是最终确定的有效路径，报错： raise Exception(“Java gateway process exited before sending the driver its port number”)
Exception: Java gateway process exited before sending the driver its port number
如果用：os.environ[‘SPARK_HOME’] = “C:/Users/tsl/AppData/Local/Programs/Python/Python35/Lib/site-packages/pyspark”
报错为：FileNotFoundError: [WinError 2] 系统找不到指定的文件。
，注意教程pycharm在windows下配置，在C:\Windows\System32\cmd.exe,以管理员权限打开，然后再运行E:\1\hadoop-2.7.1\hadoop-2.7.1\bin\winutils\bin\winutils.exe chmod 777 C:\tmp\hive，退出，再以管理员员身份进入cmd，输入pyspark,两个窗口区别：是否是以管理员身份打开的；
