Subject [jira] [Created] (SPARK-21980) References in grouping functions should be indexed with resolver
Date Tue, 12 Sep 2017 09:25:00 GMT
Feng Zhu created SPARK-21980:
--------------------------------

             Summary: References in grouping functions should be indexed with resolver
                 Key: SPARK-21980
                 URL: https://issues.apache.org/jira/browse/SPARK-21980
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 2.2.0, 2.1.1, 2.1.0
            Reporter: Feng Zhu


In our spark-2.1 cluster, when users sumbit queries like

{code:sql}
select a, grouping(b), sum(c) from table group by a, b with cube
{code}

It works well. However, when the query is 

{code:sql}
select a, grouping(B), sum(c) from table group by a, b with cube
{code}

We will get the exception:

{code:java}
org.apache.spark.sql.AnalysisException: Column of grouping (B#11) can't be found in grouping
columns a#10,b#11
{code}

The root cause is the replaceGroupingFunc's  incorrect logic in ResolveGroupingAnalytics
 rule
