PySpark definetly works for me in ipython notebook. A good way to debug is
do "setMaster("local")" in your python sc object, see if that works. Then
from there, modify it to point to the real spark server.
Also, I added a hack where i did sys.path.insert the path to pyspark in my
python note book to get it working properly.
You can try these instructions out if you want which i recently put
together based on some other stuff online + a few minor modifications .
