I installed Spark, ran the sbt assembly, and can open bin/pyspark with no problem. However, I am running into problems loading the pyspark module into ipython. I'm getting the following error:
In [1]: import pyspark

In my environment (using docker and the image sequenceiq/spark:1.1.0-ubuntu), I ran in to this. If you look at the pyspark shell script, you'll see that you need a few things added to your PYTHONPATH:
export PYTHONPATH=$SPARK_HOME/python/:$PYTHONPATH
export PYTHONPATH=$SPARK_HOME/python/lib/py4j-0.8.2.1-src.zip:$PYTHONPATH
That worked in ipython for me.
Update: as noted in the comments, the name of the py4j zip file changes with each Spark release, so look around for the right name.
