Hi All,
I get the below stack trace when I am using Zeppelin. If I don't use
Zeppelin all my client Jobs are running fine. I am using spark 2.1.0
I am not sure why Zeppelin is unable to create a SparkContext ? but then it
says it created SparkSession so it doesn't seem to make a lot of sense. any
idea?
Thanks!
