Ich bin neu mit Apache Spark und habe anscheinend Apache-Spark mit Homebrew in meinem MacBook installiert:

Ich würde gerne anfangen zu spielen, um mehr über MLlib zu erfahren. Ich benutze Pycharm jedoch, um Skripte in Python zu schreiben. Das Problem ist: Wenn ich zu Pycharm gehe und versuche, pyspark aufzurufen, kann Pycharm das Modul nicht finden. Ich habe versucht, den Pfad zu Pycharm wie folgt hinzuzufügen:
Dann habe ich in einem Blog Folgendes versucht:
import os
import sys
# Path for spark source folder
os.environ['SPARK_HOME']="/Users/user/Apps/spark-1.5.2-bin-hadoop2.4"
# Append pyspark to Python Path
sys.path.append("/Users/user/Apps/spark-1.5.2-bin-hadoop2.4/python/pyspark")
try:
from pyspark import SparkContext
from pyspark import SparkConf
print ("Successfully imported Spark Modules")
except ImportError as e:
print ("Can not import Spark Modules", e)
sys.exit(1)
Und kann immer noch nicht anfangen, PySpark mit Pycharm zu verwenden, eine Idee, wie man PyCharm mit Apache-Pyspark "verknüpft"?.
Aktualisieren:
Dann suche ich nach Apache-Spark- und Python-Pfad, um die Umgebungsvariablen von Pycharm festzulegen:
Apache-Funken-Pfad:
user@MacBook-Pro-User-2:~$ brew info apache-spark
apache-spark: stable 1.6.0, HEAD
Engine for large-scale data processing
https://spark.apache.org/
/usr/local/Cellar/apache-spark/1.5.1 (649 files, 302.9M) *
Poured from bottle
From: https://github.com/Homebrew/homebrew/blob/master/Library/Formula/apache-spark.rb
Python-Pfad:
user@MacBook-Pro-User-2:~$ brew info python
python: stable 2.7.11 (bottled), HEAD
Interpreted, interactive, object-oriented programming language
https://www.python.org
/usr/local/Cellar/python/2.7.10_2 (4,965 files, 66.9M) *
Dann habe ich mit den obigen Informationen versucht, die Umgebungsvariablen wie folgt festzulegen:
Irgendeine Idee, wie man Pycharm richtig mit pyspark verbindet?
Wenn ich dann ein Python-Skript mit der obigen Konfiguration ausführe, habe ich diese Ausnahme:
/usr/local/Cellar/python/2.7.10_2/Frameworks/Python.framework/Versions/2.7/bin/python2.7 /Users/user/PycharmProjects/spark_examples/test_1.py
Traceback (most recent call last):
File "/Users/user/PycharmProjects/spark_examples/test_1.py", line 1, in <module>
from pyspark import SparkContext
ImportError: No module named pyspark
AKTUALISIEREN: Dann habe ich diese von @ zero323 vorgeschlagenen Konfigurationen ausprobiert
Konfiguration 1:
/usr/local/Cellar/apache-spark/1.5.1/
aus:
user@MacBook-Pro-de-User-2:/usr/local/Cellar/apache-spark/1.5.1$ ls

Konfiguration 2:
