ubuntu下pyspark的安装

1.安装jkd1.8(这里不再描述)

2.直接在终端输入pip install pyspark(官网提供的最简单的一种安装方式)

过程如下:

安装完成后, 终端输入pyspark,启动pyspark出错......

tan@tan-Precision-Tower-3620:~$ pyspark
JAVA_HOME is not set

解决方法:

找到pyspark的安装路径

tan@tan-Precision-Tower-3620:~$ pip install pyspark
Requirement already satisfied: pyspark in ./anaconda3/lib/python3.6/site-packages
Requirement already satisfied: py4j==0.10.7 in ./anaconda3/lib/python3.6/site-packages (from pyspark)

找到路径后,在load-spark-env.sh文件中加上jdk的安装路径即可

export JAVA_HOME=/home/tan/jdk1.8.0_181

保存之后, 再次在终端输入pyspark, 成功启动pyspark

tan@tan-Precision-Tower-3620:~$ pyspark
