| # 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. |
| # |
