How to change PYSPARK_PYTHON from 2.7 to 3.6?

[cqpaul]

I have got an Exception as below, hope some one can help to solve it, thanks.

Python in worker has different version 2.7 than that in driver 3.6, PySpark cannot run with different minor versions.Please check environment variables PYSPARK_PYTHON and PYSPARK_DRIVER_PYTHON are correctly set.

docker exec -it -e PYSPARK_PYTHON=python3 spark-master /spark/bin/pyspark

ok @Flyfoxs this works for the master but not for the worker?
how can i make sure the worker also starts up python 3?
