Newbie question

Hello,
I am new to Spark and have a most likely basic question - can I override a method from SparkContext?
Thanks

For example to add some functionality there.
I understand I can have extended SparkContext as an implicit class to add new methods that can be invoked on SparkContext, but I want to see if I can override existing one.

Yes , you can do it unless the method is marked static/final.Most of the methods in SparkContext are marked static so you can't over ride them definitely , else over ride would work usually.
