-------------------------------
Summary: Distinct functions don't work properly after
hive.map.groupby.sorted is default to true
Key: HIVE-13768
URL: https://issues.apache.org/jira/browse/HIVE-13768
Project: Hive
Issue Type: Bug
Components: Query Planning
Affects Versions: 2.0.0
Reporter: Aihua Xu
Assignee: Aihua Xu
HIVE-12325 changes hive.map.groupby.sorted default value to true. The following
{{select count(distinct) from t1;}} will return incorrect result now. In the
older version, if you set hive.map.groupby.sorted to true, seems it will also
return incorrect result.
