Write and run pyspark in IntelliJ IDEA

Question

i am trying to work with Pyspark in IntelliJ but i cannot figure out how to correctly install it/setup the project. I can work with Python in IntelliJ and I can use the pyspark shell but I cannot tell IntelliJ how to find the Spark files (import pyspark results in "ImportError: No module named pyspark").

Any tipps on how to include/import spark so that IntelliJ can work with it are appreciated.

Thanks.

UPDATE:

I tried this piece of code:

from pyspark import SparkContext, SparkConf
spark_conf = SparkConf().setAppName("scavenge some logs")
spark_context = SparkContext(conf=spark_conf)
address = "C:\test.txt"
log = spark_context.textFile(address)

my_result = log.filter(lambda x: 'foo' in x).saveAsTextFile('C:\my_result')

with the following error messages:

Traceback (most recent call last):
File "C:/Users/U546816/IdeaProjects/sparktestC/.idea/sparktestfile", line 2, in <module>
spark_conf = SparkConf().setAppName("scavenge some logs")

return self.data[key.upper()]
KeyError: 'SPARK_HOME'

Set the env path for (SPARK_HOME and PYTHONPATH) in your program run/debug configuration.

For instance:

SPARK_HOME=/Users/<username>/javalibs/spark-1.5.0-bin-hadoop2.4/python/
PYTHON_PATH=/Users/<username>/javalibs/spark-1.5.0-bin-hadoop2.4/python/pyspark
