             Summary: Remove getting SQLContext from SparkSession.wrapped()
                 Key: ZEPPELIN-1270
                 URL: https://issues.apache.org/jira/browse/ZEPPELIN-1270
             Project: Zeppelin
          Issue Type: Improvement
    Affects Versions: 0.7.0
            Reporter: Jeff Zhang
            Assignee: Jeff Zhang
            Priority: Minor


SparkSession.wrapped is only for spark 2.0 preview, it is not supported in spark 2.0 release. So I think we can remove that piece of code. Otherwise we will get the following error in log which might be a little confusing.
