PySpark异常与GraphFrames

Question

我正在用PySpark和GraphFrames构建一个简单的网络图(运行在Google上)

vertices = spark.createDataFrame([
  ("a", "Alice", 34),
  ("b", "Bob", 36),
  ("c", "Charlie", 30),
  ("d", "David", 29),
  ("e", "Esther", 32),
  ("f", "Fanny", 36),
  ("g", "Gabby", 60)], 

    ["id", "name", "age"])

edges = spark.createDataFrame([
  ("a", "b", "friend"),
  ("b", "c", "follow"),
  ("c", "b", "follow"),
  ("f", "c", "follow"),
  ("e", "f", "follow"),
  ("e", "d", "friend"),
  ("d", "a", "friend"),
  ("a", "e", "friend")
], ["src", "dst", "relationship"])

g = GraphFrame(vertices, edges)

然后，我试着运行“标签代理”。

result = g.labelPropagation(maxIter=5)

但我得到了以下错误：

Py4JJavaError: An error occurred while calling o164.run.
: org.apache.spark.SparkException: Job aborted due to stage failure: Task 0 in stage 19.0 failed 4 times, most recent failure: Lost task 0.3 in stage 19.0 (TID 829, cluster-network-graph-w-12.c.myproject-bi.internal, executor 2): java.lang.ClassNotFoundException: org.graphframes.GraphFrame$$anonfun$5

它看起来包'GraphFrame‘是不可用的-但只有当我运行标签传播。我怎么才能修好它？

Answer 1

我使用以下参数进行了求解

import pyspark
from pyspark.sql import SparkSession

conf = pyspark.SparkConf().setAll([('spark.jars', 'gs://spark-lib/bigquery/spark-bigquery-latest.jar'),
                                   ('spark.jars.packages', 'graphframes:graphframes:0.7.0-spark2.3-s_2.11')])

spark = SparkSession.builder \
  .appName('testing bq')\
  .config(conf=conf) \
  .getOrCreate()

Answer 2

在google中，这似乎是一个已知的图形帧问题。

创建一个python文件并添加以下行，然后运行它：

from setuptools import setup

setup(name='graphframes',
version='0.5.10',
packages=['graphframes', 'graphframes.lib']
)
