DF.topandas() — не удалось найти двоичный файл winutils в двоичном пути Hadoop. ⇐ Python

[Anonymous]

Я запускаю огромный текстовый файл, используя PyCharm и PySpark.

Вот что я пытаюсь сделать:

spark_home = os.environ.get('SPARK_HOME', None)
os.environ["SPARK_HOME"] = "C:\spark-2.3.0-bin-hadoop2.7"
import pyspark
from pyspark import SparkContext, SparkConf
from pyspark.sql import SparkSession
conf = SparkConf()
sc = SparkContext(conf=conf)
spark = SparkSession.builder.config(conf=conf).getOrCreate()
import pandas as pd
ip = spark.read.format("csv").option("inferSchema","true").option("header","true").load(r"some other file.csv")
kw = pd.read_csv(r"some file.csv",encoding='ISO-8859-1',index_col=False,error_bad_lines=False)
for i in range(len(kw)):
rx = '(?i)'+kw.Keywords
ip = ip.where(~ip['Content'].rlike(rx))
op = ip.toPandas()
op.to_csv(r'something.csv',encoding='utf-8')


Однако PyCharm выдает мне эту ошибку:

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

Я просто не понимаю, почему .toPandas() не работает. Версия Spark — 2.3. Что-то изменилось в этой версии, о чем я не знаю? Я запустил этот код на другом компьютере с искрой 2.2, и он работал нормально.

Я даже изменил строку экспорта на что-то вроде этого

op = ip.where(ip['Content'].rlike(rx)).toPandas()


По-прежнему получаю ту же ошибку. Что я делаю неправильно? Есть ли другой способ экспорта pyspark.sql.dataframe.DataFrame в .csv без ущерба для производительности?

EDITED
Я также пробовал использовать:

ip.write.csv('file.csv')


Теперь я получаю следующую ошибку:

Traceback (most recent call last):
