I got an illegal argument error with 2.4.6.

I then pointed my Jupiter notebook  to 3.0 version and it worked as expected. 
Using same .ipnyb file.

I was following this machine learning example.
“Your First Apache Spark ML Model” by Favio Vázquez https://towardsdatascience.com/your-first-apache-spark-ml-model-d2bb82b599dd 

In the example he is using version 3.0 so I assumed I got the error because I am using different version (2.4.6).

afaik It has been there since  Spark 2.0 in 2015.   Not certain about Spark 1.5/1.6

I first ran the  command 

For sanity check of my dataFrame.

I wasn't impressed with the display.

I then ran 
df.toPandas() in Jupiter Notebook.

Now the display is really good looking .

Is toPandas() a new function which became available in Spark 3.0 ?
