나는 아파치 스파크를 처음 사용했으며 분명히 내 맥북에 홈브류와 함께 아파치 스파크를 설치했습니다.

MLlib에 대해 자세히 알아보기 위해 게임을 시작하고 싶습니다. 그러나 나는 Pycharm을 사용하여 파이썬으로 스크립트를 작성합니다. 문제는 Pycharm으로 이동하여 pyspark를 호출하려고하면 Pycharm이 모듈을 찾을 수 없다는 것입니다. 다음과 같이 Pycharm에 경로를 추가해 보았습니다.
그런 다음 블로그에서 이것을 시도했습니다.
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)
그리고 PyCharm과 함께 PySpark를 사용할 수 없습니다. PyCharm을 apache-pyspark와 "연결"하는 방법에 대한 아이디어가 있습니까?
최신 정보:
그런 다음 Pycharm의 환경 변수를 설정하기 위해 apache-spark 및 python 경로를 검색합니다.
아파치 스파크 경로 :
user@MacBook-Pro-User-2:~$ brew info apache-spark

그런 다음 위의 정보를 사용하여 다음과 같이 환경 변수를 설정하려고했습니다.
Pycharm을 pyspark와 올바르게 연결하는 방법에 대한 아이디어가 있습니까?
그런 다음 위의 구성으로 파이썬 스크립트를 실행할 때 다음 예외가 있습니다.
