下面是我用来将bigquery表导入到pyspark集群(dataproc)并在其上运行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。它用.printschema()返回导入的df的模式,但是当我尝试运行.show()或.fit()时,它抛出以下错误。
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)
下面是我得到的错误:

请使用0.16.1及更高版本的spark bigquery连接器,在
gs://spark-lib/bigquery/spark-bigquery-with-dependencies_2.11-0.16.1.jar
以及gs://spark-lib/bigquery/spark-bigquery-with-dependencies_2.12-0.16.1.jar
(基于spark的scala版本)。它也可以从maven中央存储库获得。lsmepo6l2#
今天上午我也遇到过这个问题。在创建dataproc集群时,我使用了gs://spark lib/bigquery/spark-bigquery-latest.jar。
--属性spark:spark.jars=gs://spark lib/bigquery/spark-bigquery-latest.jar
这个连接器昨天从2.11更新到了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。
--属性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项目上创建:https://github.com/googleclouddataproc/spark-bigquery-connector/issues/187
