Hi I have a DF which contains Json string so the value is like {"key": Value, "anotherKey": anotherValue}, so when I am trying to write the DF containing this string to the CSV, spark is ​adding NUL character af the front of this line and at the end, so the final line is like

NUL{"​key": Value, "anotherKey": anotherValue}NUL

I really don't want this to happen, how can I prevent this?

The code I am using is

df.coalesce(1).write.format("csv").option("header", false).option("quote", "").save(path)​
