PySpark in PyCharm on a remote server
1、确保remote端Python、spark安装正确
2、remote端安装、设置
vi /etc/profile
添加一行：PYTHONPATH=$SPARK_HOME/python/:$SPARK_HOME/python/lib/py4j-0.8.2.1-src.zip
source /etc/profile
# 安装pip 和 py4j
下载pip-7.1.2.tar
tar -xvf pip-7.1.2.tar
cd pip-7.1.2
python setup.py install
pip install py4j
# 避免ssh时tty检测
cd /etc
chmod 640 sudoers
vi /etc/sudoers
#Default requiretty
3、本地Pycharm设置
File > Settings > Project Interpreter:
Project Interpreter > Add remote（前提：remote端python安装成功）:
注意，这里的Python路径为python interpreter path，如果python安装在其它路径，要把路径改过来
Run > Edit Configuration （前提：虚拟机中共享本地目录成功）:
此处我配置映射是在Tools中进行的
Tools > Dployment > Configuration
4、测试
import os
import sys
os.environ[‘SPARK_HOME‘] = ‘/root/spark-1.4.0-bin-hadoop2.6‘
sys.path.append("/root/spark-1.4.0-bin-hadoop2.6/python")
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)
Result: ssh://[email protected]:22/usr/bin/python -u /home/hadoop/TestFile/pysparkProgram/Mainprogram.pySuccessfully imported Spark Modules Process finished with exit code 0
或者：
import sys
sys.path.append("/root/programs/spark-1.4.0-bin-hadoop2.6/python")
try:
import numpy as np
import scipy.sparse as sps
from pyspark.mllib.linalg import Vectors
dv1 = np.array([1.0, 0.0, 3.0])
dv2 = [1.0, 0.0, 3.0]
sv1 = Vectors.sparse(3, [0, 2], [1.0, 3.0])
sv2 = sps.csc_matrix((np.array([1.0, 3.0]), np.array([0, 2]), np.array([0, 2])), shape=(3, 1))
print(sv2)
except ImportError as e:
print("Can not import Spark Modules", e)
sys.exit(1)
Result ssh://[email protected]:22/usr/bin/python -u /home/hadoop/TestFile/pysparkProgram/Mainprogram.py (0, 0) 1.0 (2, 0) 3.0 Process finished with exit code 0
