----------------------------------
Summary: Should check determinism when pushing predicates down
through aggregation
Key: SPARK-20246
URL: https://issues.apache.org/jira/browse/SPARK-20246
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.1.0
Reporter: Weiluo Ren
`
import org.apache.spark.sql.functions._
spark.range(1,1000).distinct.withColumn("random", rand()).filter(col("random")
> 0.3).orderBy("random").show
`
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.
