[Python] DF.topandas() - Failed to locate the winutils binary in the hadoop binary path

I am running a huge text file using PyCharm and PySpark.

This is what I am trying to do:

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')


However, PyCharm is throwing me this error:

To adjust logging level use sc.setLogLevel(newLevel). For SparkR, use setLogLevel(newLevel).
2018-06-08 11:31:52 WARN Utils:66 - Truncated the string representation of a plan since it was too large. This behavior can be adjusted by setting 'spark.debug.maxToStringFields' in SparkEnv.conf.

I am just not getting why .toPandas() is not working. Spark version is 2.3. Has something changed in this version that I am unaware of? I ran this code in a different machine with spark 2.2, and it ran fine.

I even changed the export line to something like this

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


Still getting the same error. What am I doing wrong? Is there some other way of exporting pyspark.sql.dataframe.DataFrame to a .csv without compromising on performance?

EDITED I also tried using:

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


Now i am getting the following error:

Traceback (most recent call last):
File "somefile.csv", line 21, in <module>

Adding the stacktrace:

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