Problem

I need to use anaconda for %livy.pyspark. Now, it is using the default python2.6

%livy.pyspark
import sys
print(sys.path)

How can I get this working with python-3.5?

Solution

Based on https://issues.apache.org/jira/browse/ZEPPELIN-1609, there is a new pyspark implemented within livy - %livy.pyspark3. This is delivered in Zeppelin 0.7 that comes with HDP 2.6.

For now, do the following:

> go to Ambari UI -> Spark -> Config -> Advanced livy-env -> content
-> set: export PYSPARK_PYTHON=/opt/anaconda/bin/python - path to new python version
-> set: export PYSPARK_DRIVER_PYTHON=/opt/anaconda/bin/python - path to new python version
> save the changes
> Restart all required services

livy-env.sh is shared by all the sessions which means one livy instance can only run one version of python. I would recommend user to use spark configuration spark.pyspark.driver.python and spark.pyspark.python in spark2 (HDP 2.6) so that each session can set his own python version. https://issues.apache.org/jira/browse/SPARK-13081
