apache-spark - org.apache.spark.SparkException：无法初始化类 com.google.cloud.spark.bigquery.SparkBigQueryConnectorUserAgentProvider

问题描述

下面是我用来将 bigquery 表导入到我的 PySpark 集群（dataproc）然后在其上运行 fp-growth 算法的代码。但是，今天当我运行相同的代码时，它抛出了一个错误。它使用 .printSchema() 返回导入的 df 的架构，但是当我尝试运行 .show() 或 .fit() 时，它会引发以下错误。

from pyspark.sql import SparkSession
from pyspark.sql.functions import col, split
from pyspark.sql.types import ArrayType, IntegerType
from pyspark.ml.fpm import FPGrowth
from pyspark.sql.functions import concat_ws
spark = SparkSession.builder.appName('Jupyter BigQuery Storage').config('spark.jars','gs://spark-lib/bigquery/spark-bigquery-latest.jar').getOrCreate()

table = "project_name.dataset_name.test_table"
df = spark.read.format("bigquery").option("table",table).load()
df.printSchema()


df = df.withColumn(
    "item",
    split(col("item"), ",").cast(ArrayType(IntegerType())).alias("item")
    )

df.printSchema()

df.show(2)

fpGrowth = FPGrowth(itemsCol="item", minSupport=0.01, minConfidence=0.01)
model = fpGrowth.fit(df)

以下是我得到的错误：

解决方案

我今天早上也遇到了这个问题。我在创建 DataProc 集群时使用了 gs://spark-lib/bigquery/spark-bigquery-latest.jar。

--properties spark:spark.jars=gs://spark-lib/bigquery/spark-bigquery-latest.jar

此连接器昨天从 2.11 更新到 2.12。

我不得不降级到 spark-bigquery-latest_2.11.jar 连接器来修复我的脚本。

--properties spark:spark.jars=gs://spark-lib/bigquery/spark-bigquery-latest_2.11.jar

新 2.12 驱动程序的问题已在 Github 项目中创建：https ://github.com/GoogleCloudDataproc/spark-bigquery-connector/issues/187
