    ubuntu自带的python 版本是2.7，

    我们要把pyspark默认改成anaconda python 3.6

    You can specify the version of Python for the driver by setting the appropriate environment variables in the ./conf/spark-env.sh file. If it doesn't already exist, you can use the spark-env.sh.templatefile provided which also includes lots of other variables.

    Here is a simple example of a spark-env.sh file to set the relevant Python environment variables:

    #!/usr/bin/env bash

     

    # This file is sourced when running various Spark programs.

    export PYSPARK_PYTHON=/usr/bin/python3

    export PYSPARK_DRIVER_PYTHON=/usr/bin/ipython

    In this case it sets the version of Python used by the workers/executors to Python3 and the driver version of Python to iPython for a nicer shell to work in.

     

    意思就是把spark文件夹下的./conf/spark-env.sh.tempalte 重命名成spark-env.sh

    然后添加如下内容：

    # This file is sourced when running various Spark programs.

    export PYSPARK_PYTHON=/usr/bin/python3

    export PYSPARK_DRIVER_PYTHON=/usr/bin/ipython

     

    重启spark 即可
