在pip安装pyspark之后运行pyspark [英] Running pyspark after pip install pyspark

问题描述

我想在家用计算机上安装pyspark.我做到了

I wanted to install pyspark on my home machine. I did

pip install pyspark
pip install jupyter

两者看起来都很好.

但是当我尝试运行pyspark时，我会得到

But when I try to run pyspark I get

pyspark
Could not find valid SPARK_HOME while searching ['/home/user', '/home/user/.local/bin']

SPARK_HOME应该设置为什么?

推荐答案

我刚刚遇到了同样的问题，但是事实证明，pip install pyspark下载的火花分布在本地模式下效果很好.点子没有设置适当的SPARK_HOME.但是当我手动设置此项时，pyspark就像一个超级按钮一样工作(无需下载任何其他软件包).

I just faced the same issue, but it turned out that pip install pyspark downloads spark distirbution that works well in local mode. Pip just doesn't set appropriate SPARK_HOME. But when I set this manually, pyspark works like a charm (without downloading any additional packages).

$ pip3 install --user pyspark
