Could you try setting zeppelin.pyspark.python in the interpreter setting to the
matching Python 3? "python3" in your example below.

Subject: Fwd: Zeppelin error when trying to run pyspark using python3
To: <[email protected]>
Hello,
Yesterday I installed a Spark server with Zeppelin and, while testing in a new
notebook, I realized that pyspark is using Python 2.7.9. I have Python 3.4.3
installed and some other things I can tell if you later.
Looking for how to use python3, I found this post [1]. I tried setting those
env variables in .bashrc and zeppelin-env.sh as
export PYSPARK_PYTHON="python3"
export PYSPARK_DRIVER_PYTHON="ipython3"
When I run ./bin/pyspark I get
paulo_filho@spark:~$ $SPARK_HOME/bin/pyspark
Python 3.4.3 (default, Mar 26 2015, 22:03:40)
Type "copyright", "credits" or "license" for more information.
IPython 4.0.0 -- An enhanced Interactive Python.

Using Python version 3.4.3 (default, Mar 26 2015 22:03:40)
but Zeppelin didn't work. Instead, I got the error below:
%pyspark import sys
print(sys.version_info) sys.version_info(major=2, minor=7,
micro=9, releaselevel='final', serial=0)
%pyspark bankText = sc.textFile("/home/paulo_filho/data/bank.csv")
print(bankText.take(2))

I noticed that in Zeppelin's "Interpreter" section there's a
config
zeppelin.pyspark.python python
I've already tried to change that, but I got the same error
always.
So, I'm here asking for your help. =)
Thanks!
