Files listed here will be added to the `PYTHONPATH` and shipped to remote worker machines.
Code dependencies can be added to an existing SparkContext using its `addPyFile()` method.
+You can set [system properties](configuration.html#system-properties)
+using `SparkContext.setSystemProperty()` class method *before*
+instantiating SparkContext. For example, to set the amount of memory
+per executor process:

+{% highlight python %}

+SparkContext.setSystemProperty('spark.executor.memory', '2g')
+sc = SparkContext("local", "App Name")
