Subject: Re: pyspark with jar
I actually *just* figured it out. Zeppelin has sqlContext "already created and
exposed" (https://zeppelin.incubator.apache.org/docs/interpreter/spark.html).
So when I do "sqlContext = SQLContext(sc)" I overwrite sqlContext. Then
Zeppelin cannot see this new sqlContext.
Anyway, anyone out there experiencing this problem, do NOT initialize
sqlContext and it works fine.
