Installing

First, you need to have Apache Spark installed. Follow the instructions here: http://spark.apache.org/docs/latest/

Then you can do:

pip install Orange3-spark

or install the add-on from the Orange’s Options | Add-ons menu. Note, if installing from Add-ons menu, the installation may fail if not all requirements are satisfiable.

If you require ODBC connectivity, you need to install pyodbc (which requires sql.h available if built with pip – that’s unixodbc-dev package on Linux).

If install is ok, you should see a new section in Orange containing a series of widgets from Spark ML API.
