> I have df where column1 is struct type and there is 1M rows.
> (sample data from https://issues.apache.org/jira/browse/SPARK-16320)
> {code}
> df.where("column1 is not null").count()
> {code}
> gives:
> 1M in Spark 1.6
> *0* in Spark 2.0
> Is there a change in IS NOT NULL behaviour in Spark 2.0 ?
