JESSE CHEN created SPARK-13863:
----------------------------------
Summary: TPCDS query 66 returns wrong results compared to TPC
official result set
Key: SPARK-13863
URL: https://issues.apache.org/jira/browse/SPARK-13863
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 1.6.0
Reporter: JESSE CHEN
Testing Spark SQL using TPC queries. Query 49 returns wrong results compared to
official result set. This is at 1GB SF (validation run).
SparkSQL has right answer but in wrong order (and there is an 'order by' in the
query).
Actual results:
