如何将PyCharm与PySpark连接？

Question

我是apache spark的新手,显然我在我的macbook中用自制软件安装了apache-spark:

我想开始玩,以了解有关MLlib的更多信息.但是,我使用Pycharm在python中编写脚本.问题是:当我去Pycharm并尝试调用pyspark时,Pycharm无法找到该模块.我尝试将路径添加到Pycharm,如下所示:

然后从博客我试过这个:

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)

并且仍然无法开始使用Pycharm与Pycharm,任何想法如何"链接"PyCharm与apache-pyspark？

更新:

然后我搜索apache-spark和python路径以设置Pycharm的环境变量:

apache-spark路径:

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路径:

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) *

然后用上面的信息我试着设置环境变量如下:

知道如何正确链接Pycharm与pyspark？

然后,当我运行具有上述配置的python脚本时,我有以下异常:

/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

更新: 然后我尝试了@ zero323提出的配置

配置1:

/usr/local/Cellar/apache-spark/1.5.1/ 

出:

 user@MacBook-Pro-de-User-2:/usr/local/Cellar/apache-spark/1.5.1$ ls
CHANGES.txt           NOTICE                libexec/
INSTALL_RECEIPT.json  README.md
LICENSE               bin/

配置2:

/usr/local/Cellar/apache-spark/1.5.1/libexec 

出:

user@MacBook-Pro-de-User-2:/usr/local/Cellar/apache-spark/1.5.1/libexec$ ls
R/        bin/      data/     examples/ python/
RELEASE   conf/     ec2/      lib/      sbin/

Answer 1

使用PySpark包(Spark 2.2.0及更高版本)

随着SPARK-1267被合并,你应该能够通过简化流程pip在您使用PyCharm发展环境中安装的火花.

1. 转到文件 - > 设置 - > 项目解释器

2. 单击"安装"按钮并搜索PySpark

   

3. 单击"安装包"按钮.

手动提供用户提供的Spark安装

创建运行配置:

1. 转到运行 - > 编辑配置
2. 添加新的Python配置
3. 设置脚本路径,使其指向要执行的脚本

4. 编辑环境变量字段,使其至少包含:

   • SPARK_HOME - 它应该指向Spark安装目录.它应包含的目录,例如bin(具有spark-submit,spark-shell等)和conf(用spark-defaults.conf,spark-env.sh等)

   • PYTHONPATH- 它应该包含$SPARK_HOME/python并且可选地$SPARK_HOME/python/lib/py4j-some-version.src.zip否则不可用.some-version应匹配给定Spark安装使用的Py4J版本(0.8.2.1 - 1.5,0.9 - 1.6,0.10.3 - 2.0,0.10.4 - 2.1,0.10.4 - 2.2,0.10.6 - 2.3)

     

5. 应用设置

将PySpark库添加到解释器路径(代码完成所需):

1. 转到文件 - > 设置 - > 项目解释器
2. 打开要与Spark一起使用的解释器的设置
3. 编辑解释器路径,使其包含路径$SPARK_HOME/python(如果需要,可以使用Py4J)
4. 保存设置

可选

1. 安装或添加与安装的Spark版本匹配的路径类型注释,以获得更好的完成和静态错误检测(免责声明 - 我是项目的作者).

最后

使用新创建的配置来运行脚本.

Answer 2

这是我在mac osx上解决这个问题的方法.

1. brew install apache-spark

2. 将其添加到〜/ .bash_profile

   export SPARK_VERSION=`ls /usr/local/Cellar/apache-spark/ | sort | tail -1`
   export SPARK_HOME="/usr/local/Cellar/apache-spark/$SPARK_VERSION/libexec"
   export PYTHONPATH=$SPARK_HOME/python/:$PYTHONPATH
   export PYTHONPATH=$SPARK_HOME/python/lib/py4j-0.9-src.zip:$PYTHONPATH
   

3. 将pyspark和py4j添加到内容根目录(使用正确的Spark版本):

   /usr/local/Cellar/apache-spark/1.6.1/libexec/python/lib/py4j-0.9-src.zip
   /usr/local/Cellar/apache-spark/1.6.1/libexec/python/lib/pyspark.zip
   

Answer 3

这是适合我的设置

设置智能感知:

1. 单击文件 - >设置 - >项目: - >项目解释器

2. 单击Project Interpreter下拉列表右侧的齿轮图标

3. 从上下文菜单中单击"更多..."

4. 选择解释器,然后单击"显示路径"图标(右下角)

5. 单击+图标两个添加以下路径:

   \ python的\ LIB\py4j-0.9-src.zip

   \ BIN\python的\ LIB\pyspark.zip

6. 单击确定,确定,确定

继续测试您的新intellisense功能.

Answer 4

在pycharm(windows)中配置pyspark

File menu - settings - project interpreter - (gearshape) - more - (treebelowfunnel) - (+) - [add python folder form spark installation and then py4j-*.zip] - click ok

确保在windows环境中设置SPARK_HOME,pycharm将从那里开始.确认 :

Run menu - edit configurations - environment variables - [...] - show

(可选)在环境变量中设置SPARK_CONF_DIR.
