# In Spark <= 1.1, setting IPYTHON=1 would cause the driver to be launched using the `ipython`
|
|
# executable, while the worker would still be launched using PYSPARK_PYTHON.
|
|
#
|
|
# In Spark 1.2, we removed the documentation of the IPYTHON and IPYTHON_OPTS variables and added
|
|
# PYSPARK_DRIVER_PYTHON and PYSPARK_DRIVER_PYTHON_OPTS to allow IPython to be used for the driver.
|
|
# Now, users can simply set PYSPARK_DRIVER_PYTHON=ipython to use IPython and set
|
|
# PYSPARK_DRIVER_PYTHON_OPTS to pass options when starting the Python driver
|
|
# (e.g. PYSPARK_DRIVER_PYTHON_OPTS='notebook'). This supports full customization of the IPython
|
|
# and executor Python executables.
|
