Davies Liu created SPARK-14600: ---------------------------------- Summary: Push predicates through Expand Key: SPARK-14600 URL: https://issues.apache.org/jira/browse/SPARK-14600 Project: Spark Issue Type: Improvement Components: SQL Reporter: Davies Liu
A grouping sets will be analyzed as Aggregate(Expand(Project)), the grouping attributes came from Project, but have different meaning in Project (equal to original grouping expression) and Expand (could be original grouping expression or null), this does not make sense, because the attribute has different result in different operator, A better way could be Aggregate(Expand()), then we need to fix SQL generation. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
