【中文标题】Python Graphframes:安装依赖项时遇到问题【英文标题】:Python Graphframes: trouble installing dependencies 【发布时间】:2019-10-24 09:15:42 【问题描述】:

我正在尝试运行simple Graphframes example。我有 Python 3.6.8 和 Python 2.7.15,以及 Apache Maven 3.6.0、Java 1.8.0、Apache Spark 2.4.4 和 Scala 代码运行器版本 2.11.12。

我收到了这个错误:

An error occurred while calling o58.loadClass.
: java.lang.ClassNotFoundException: org.graphframes.GraphFramePythonAPI

我试图启动this solution,但我卡在了第 2 步。

我运行pyspark --packages graphframes:graphframes:0.7.0-spark2.4-s_2.11 并得到以下输出:

不用说这不是预期的输出,所有超时的链接都会导致 404。我的电脑在代理后面,但代理设置是在 Maven 设置文件中配置的,我知道它们可以正常工作。

还有其他代理设置需要更改吗?是否有另一种安装这些依赖项的方法?

我将我的/usr/share/jupyter/kernels/python3/kernel.json 文件更改为:


 "argv": [
  "/usr/bin/python3",
  "-m",
  "ipykernel_launcher",
  "-f",
  "connection_file"
 ],
 "env": 
  "PYSPARK_SUBMIT_ARGS": "--packages graphframes:graphframes:0.7.0-spark2.4-s_2.11 --master local[10] pyspark-shell"
 ,
 "display_name": "Python 3",
 "language": "python"

然后尝试在 Jupyter Notebook 中运行我的 Python 脚本。这没有用。事实上,现在只要我运行我的 Python 脚本,它就会导致这个错误(在它导入所需的导入之后,它会崩溃)

我调整了我的 Firefox 并自己下载了文件。

-rw-rw-r-- 1 jessica jessica   381110 Oct 22 12:17 graphframes-0.7.0-spark2.4-s_2.11.jar
-rw-rw-r-- 1 jessica jessica     2541 Oct 22 12:14 graphframes-0.7.0-spark2.4-s_2.11.pom

然后我运行mvn install:install-file -Dfile=graphframes-0.7.0-spark2.4-s_2.11.jar -DpomFile=graphframes-0.7.0-spark2.4-s_2.11.pom,尽管该过程成功,但我仍然无法运行我的脚本(仍然出于相同的原因)。但是,现在我的 maven 存储库中有一个 graphframes 文件夹,其中包含所有必需的文件。

我已经卸载并重新安装了 Jupyter、notebook、graphframes、toree、iPython 并添加了 Anaconda - 全部适用于 Python 2.7 和 Python 3。我无法为 Python/Pyspark 安装 Apache Toree 内核 (v0.3.0)(我确实有 SQL 和 Scala,显然它不再支持 Python/Pyspark 内核 - 也欢迎解决此问题)。

我的SPARK_HOME=~/spark/spark-2.2.0-bin-hadoop2.7 变量以及PYSPARK_DRIVER_PYTHON="jupyter"PYSPARK_DRIVER_PYTHON_OPTS="notebook" 也已设置。

【参考方案1】:

我使用advice from this site解决了这个问题。

长话短说,把罐子直接放在$SPARK_HOME/jars

【讨论】:

【参考方案2】:

我看到的和你看到的一样。问题在于托管工件shut down on May 2021 的存储库bintray。当您为图框指定 Maven 坐标时,您还应该 provide the current repository 托管此工件。

按以下方式执行 PySpark 对我有用。

pyspark \
    --packages graphframes:graphframes:0.8.1-spark2.4-s_2.11 \
    --repositories https://repos.spark-packages.org

【参考方案3】:

进一步推进简韦恩的回答。

from pyspark.sql import SparkSession

spark = (
    SparkSession
    .builder
    .master('yarn')
    .appName('GraphFrames_Test')
    .config("spark.jars.packages", "graphframes:graphframes:0.8.1-spark2.4-s_2.11")
    .config("spark.jars.repositories", "https://repos.spark-packages.org")
    .getOrCreate()
    )
