Spark – Error “A master URL must be set in your configuration” when submitting an app

Where is the sparkContext object defined, is it inside the main function?

I too faced the same problem, the mistake which i did was i initiated the sparkContext outside the main function and inside the class.

When I initiated it inside the main function, it worked fine.
