Paulo Haddad created ZEPPELIN-314:
-------------------------------------
Summary: pyspark is not responding for Python 3
Key: ZEPPELIN-314
URL: https://issues.apache.org/jira/browse/ZEPPELIN-314
Project: Zeppelin
Issue Type: Bug
Environment: Ubuntu 15.04
from apt: OpenJDK 1.8.0_45, Maven 3.3.3, Python 3.4.3
built from site files: Scala 2.11.7, Spark 1.5.0, Zeppelin 0.5.0 from git
(commit a731b815e12a)
Reporter: Paulo Haddad
Looking for how to use python3, I found this post [1]. I tried setting those
env variables in .bashrc and zeppelin-env.sh as
{quote}
export PYSPARK_PYTHON="python3"
export PYSPARK_DRIVER_PYTHON="ipython3"
{quote}
When I run ./bin/pyspark I get
{quote}
paulo_filho@spark:~$ $SPARK_HOME/bin/pyspark
Python 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)}}
{quote}
sys.version_info(major=2, minor=7, micro=9, releaselevel='final', serial=0)
{quote}
{{%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}}
When I change it to python3, I get
{{%pyspark}}
{{print(list(range(10)))}}
{quote}
pyspark is not responding
{quote}
I don't know what to do.
Thanks!
