I have pyspark initiated in the local mode with the aim of learning. Everything almost going well until i tried to write and save a dataframe into a csv file using this code: even i have made the env this dosn't work please help me to get over that
days = df1.select('days').where("days BETWEEN '2020-01-01' AND '2020-01-31'").distinct().collect()
for day in days[:]:
_df = df1.where(f"days = {day[0]}")
_df.coalesce(1).write.mode("append").option("header", "true").csv("C:/Users/zeyneb ben massoud/Documents/stage")
It gives me this error meanwhile creating an empty folder with the name of the csv file without writing the file itself and i have been poking around to find a solution to it without any clue:
>#error#:
Py4JJavaError Traceback (most recent call last)
<ipython-input-28-c02692e03ad7> in <module>
