How do i setup Pyspark in Python 3 with spark-env.sh.template

Because i have this issue in my ipython3 notebook, i guess i have to change "spark-env.sh.template" somehow.

Exception: Python in worker has different version 2.7 than that in driver 3.4, PySpark cannot run with different minor versions

Spark does not yet work with Python 3.If you wish to use the Python API you will also need a Python interpreter (version 2.6 or newer).

I had the same issue when running IPYTHON=1 ./pyspark.

Ok quick fix

Edit vim pyspark and change PYSPARK_DRIVER_PYTHON="ipython" line to 

PYSPARK_DRIVER_PYTHON="ipython2"

That's it.

If you want to check where dose ipython points to,

Type which ipython in terminal and I bet that'll be

/Library/Frameworks/Python.framework/Versions/3.4/bin/ipython

**UPDATED**

The latest version of spark works well with python 3. So this may not need with the latest version.

Just set the environment variable:

export PYSPARK_PYTHON=python3

in case you want this change to be permanent add this line to pyspark script

I believe you can specify the two separately, like so:

PYSPARK_PYTHON=/opt/anaconda/bin/ipython
PYSPARK_DRIVER_PYTHON=/opt/anaconda/bin/ipython

Based on this other question Apache Spark: How to use pyspark with Python 3.
