--------------------------------
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
