 Работник Python продолжает падать в pyspark

Сообщение Anonymous »

Я использую Python 3.12.0, моя версия Java — 8, а версия pyspark — 3.5. Я установил переменные среды с помощью JAVA_HOME, SPARK_HOME и HADOOP_HOME и установил winutils.exe. Мой код работает до тех пор, пока не произойдет df.show(), и он выйдет из строя с этой ошибкой. Мой код приведен ниже, а отображаемая ошибка — ниже него.

Код: Выделить всё

from pyspark.sql import SparkSession
from pyspark.sql.functions import col

# Create a SparkSession
spark = SparkSession.builder.appName("Testing PySpark Example").getOrCreate()

sample_data = [{"name": "John    D.", "age": 30},
{"name": "Alice   G.", "age": 25},
{"name": "Bob  T.", "age": 35},
{"name": "Eve   A.", "age": 28}]

df = spark.createDataFrame(sample_data)

df.show()
Вот такая ошибка.

Код: Выделить всё

To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).

Еще одно примечание: я запускаю это в VSCode, но эта ошибка все равно возникает, когда я запускаю его в терминале в Pyspark.
Эта последняя часть включен, но я хотел, чтобы программа изначально показывала его без изменений.

Код: Выделить всё

from pyspark.sql.functions import col, regexp_replace

# Remove additional spaces in name
def remove_extra_spaces(df, column_name):
# Remove extra spaces from the specified column
df_transformed = df.withColumn(column_name, regexp_replace(col(column_name), "\\s+", " "))

return df_transformed

transformed_df = remove_extra_spaces(df, "name")

transformed_df.show()

+---+--------+
|age|    name|
