问Dataproc:使用BigQuery读写数据时使用PySpark时的错误

EN

from pyspark.sql import SparkSession
from pyspark.sql.functions import udf, col
from pyspark.sql.types import IntegerType, ArrayType, StringType
from google.cloud import bigquery

# UPDATE (2022-08-10): BQ conector added
spark = SparkSession.builder.appName('SpacyOverPySpark') \
                    .config('spark.jars.packages', 'com.google.cloud.spark:spark-bigquery-with-dependencies_2.12:0.24.2') \
                    .getOrCreate()

# ------------------ IMPORTING DATA FROM BIG QUERY --------------------------

# UPDATE (2022-08-10): This line now runs...
df = spark.read.format('bigquery').option('table', 'my-project.mydatabase.mytable').load()

# But imports the whole table, which could become expensive and not optimal
print("DataFrame shape: ", (df.count(), len(df.columns)) # 109M records & 9 columns; just need 1M records and one column: "posting"

# I tried the following, BUT with NO success:
# sql = """
# SELECT `posting`
# FROM `mentor-pilot-project.indeed.indeed-data-clean`
# LIMIT 1000000
# """
# df = spark.read.format("bigquery").load(sql)
# print("DataFrame shape: ", (df.count(), len(df.columns)))

# ------- CONTINGENCY PLAN: IMPORTING DATA FROM CLOUD STORAGE ---------------

# This section WORKS (just to enable the following sections)
# HINT: This dataframe contains 1M rows of text, under a single column: "posting"
df = spark.read.csv("gs://hidden_bucket/1M_samples.csv", header=True)

# ---------------------- EXAMPLE CUSTOM PROCESSING --------------------------

# Example Python UDF Python
def split_text(text:str) -> list:
    return text.split()

# Turning Python UDF into Spark UDF
textsplitUDF = udf(lambda z: split_text(z), ArrayType(StringType()))

# "Applying" a UDF on a Spark Dataframe (THIS WORKS OK)
df.withColumn("posting_split", textsplitUDF(col("posting")))

# ------------------ EXPORTING DATA TO BIG QUERY ----------------------------

# UPDATE (2022-08-10) The code causing the error:

# df.write.format('bigquery') \
#   .option('table', 'wordcount_dataset.wordcount_output') \
#   .save()

# has been replace by a code that successfully stores data in BQ:

df.write \
  .format('bigquery') \
  .option("temporaryGcsBucket", "my_temp_bucket_name") \
  .mode("overwrite") \
  .save("my-project.mynewdatabase.mytable")
