下载资源

• hadoop3.0.0

• spark-2.4.4-bin-without-hadoop

• winutils下载(对应hadoop3.0.1的bin目录覆盖本地hadoop的bin目录)

• jdk1.8(默认已按照配置)

• conda/anaconda(默认已安装)

注意:cdh6.3.2的spark为2.4.0但是使用2.4.0本地pyspark有bug,下载的文件可能在第一次解压缩后,如未出现目录,则需要修改文件后缀为zip,再次解压缩

python环境(推荐cmd非powershell)

spark2.4.x不支持python3.7以上版本

conda create -n pyspark2.4 python=3.7
activate pyspark2.4
pip install py4j
pip install psutil

pyspark安装方法(推荐一)

1. %SPARK_HOME%\python\pyspark目录复制到%CONDA_HOME%\pyspark2.4\Lib\site-packages下

2. pip install pyspark=2.4.4

配置环境变量(自行百度)

以下只是示例,根据实际情况修改,路径不要有空格,如果有使用mklink /J 软链接 目录路径

系统变量添加
HADOOP_HOME
E:\bigdata\ENV\hadoop-3.0.0SPARK_HOME
E:\bigdata\ENV\spark-2.4.4-bin-without-hadoopPYSPARK_PYTHON
C:\Users\zakza\anaconda3\envs\pyspark2.4\python.exePATH添加
%HADOOP_HOME%\bin
%SPARK_HOME%\bin

修改配置文件

配置一 %SPARK_HOME%\conf目录下新建spark-env.cmd文件,内容如下

FOR /F %%i IN ('hadoop classpath') DO @set SPARK_DIST_CLASSPATH=%%i

配置二 %SPARK_HOME%\conf\目录下新建log4j.properties文件,内容如下

配置Pycharm

注意:配置好环境变量重启下电脑,不然可能存在pycharm无法加载系统环境变量的情况

wc.txt

hello hadoop
hadoop spark python
flink storm spark
master slave
first
second thrid
kafka scikit-learn
flume
hive spark-streaming
hbase

wordcount测试代码

from pyspark import SparkContextif __name__ == '__main__':sc = SparkContext('local', 'WordCount')textFile = sc.textFile("wc.txt")wordCount = textFile.flatMap(lambda line: line.split(" ")).map(lambda word: (word, 1)).reduceByKey(lambda a, b: a + b)wordCount.foreach(print)

正常运行结果:

常见问题:

1. spark-shell报错Caused by: java.lang.ClassNotFoundException: org.slf4j.Logger

解决方法:见上述配置一

2. Pyspark报错ModuleNotFoundError: No module named 'resource'

解决方法:spark2.4.0存在的bug,使用spark2.4.4

3. Pyspark报错org.apache.spark.sparkexception: python worker failed to connect back

解决方法:环境变量未配置正确,检查是否遗漏,并检查pycharm的configuration的环境变量里面能够看到

其他

关于%SPARK_HOME%\python\lib下的py4j-0.10.7-src.zip,pyspark.zip(未配置运行正常),也可以尝试添加到项目
