> {code}import org.apache.spark.sql.functions._
> spark.range(1,1000).distinct.withColumn("random",
> rand()).filter(col("random") > 0.3).orderBy("random").show{code}
> gives wrong result.
> In the optimized logical plan, it shows that the filter with the
> non-deterministic predicate is pushed beneath the aggregate operator, which
> should not happen.
