Writing PySpark Dataframe to CSV Py4JJavaError - pyspark

Question

I am getting a Py4JJavaError when I try to write a PySpark Dataframe to a csv. It is creating a folder in the path with the title of my csv file but there is nothing inside of the folder. Here is my code:
students.write.mode("overwrite").csv('write_test.csv')
When I run that code I get the following error:
---------------------------------------------------------------------------

I was able to get it to work by deleting the hadoop.dll file from the folder that contained winutils.exe. I also made sure that the hadoop.dll file was located in my System32 folder. I ensured that I had all of the hadoop, spark, and java jdk installs completed correctly. I ensure that the Environment Variables were pointing to the correct directories. Also, the Java 8 jdk seems to work the best with the hadoop 2.7 configuration.
