spark-standalone集群模式下运行pyspark程序，报这个错误：

Exception: Python in worker has different version 2.6 than that in driver 2.7, PySpark cannot run with different minor versions.Please check environment variables PYSPARK_PYTHON and PYSPARK_DRIVER_PYTHON are correctly set.

原因：master节点是用的安装的anaconda的2.7的python，而二个worker节点是用的linux自带ode默认的2.6版本的python。

查看master节点的python版本

[atguigu@hadoop101 ~]$  python --version
Python 2.7.12 :: Anaconda 4.2.0 (64-bit)

查看worker节点的python版本

[atguigu@hadoop103 software]$ python --version
Python 2.6.6

解决办法：在每一个worker节点安装相同版本的anaconda，并设置好环境变量默认使用anaconda的python。
