【问题描述】：

我正在尝试使用 spark-shell 安装 PySpark 包 Graphframes ：

pyspark --packages graphframes:graphframes:0.8.1-spark3.0-s_2.12

但是，终端中出现这样的错误：

我使用的是 Ubuntu 操作系统 18.04.5 LTS

JDK版本为11.0.11

Scala 版本是 2.12.13

Spark-shel 版本为 3.0.2

我想知道是什么问题？我该如何克服这个问题？

【问题讨论】：

也许你可以从spark-packages.org/package/graphframes/graphframes 下载一个.jar 到你的本地仓库？或使用--repositories 将https://spark-packages.org/ 添加到常春藤网址。

【参考方案1】：

jar 必须从repos.spark-packages.org 下载。不幸的是，当使用 --packages 参数时，pyspark 没有检查这个 repo。如果您的机器有一个正在运行的 Maven 安装可用，解决问题的最简单方法是手动将 jar 下载到本地 Maven 存储库：

mvn org.apache.maven.plugins:maven-dependency-plugin:2.1:get
 -Dartifact=graphframes:graphframes:0.8.1-spark3.0-s_2.12 
 -DrepoUrl=https://repos.spark-packages.org

此命令会将 jar（以及所有必需的依赖项，如果有）下载到您的本地 Maven 存储库/root/.m2/repository。从这个位置pyspark可以拿起罐​​子。
