[jira] [Commented] (KYLIN-1980) TopN issue: result not consistent
with hive
[ https://issues.apache.org/jira/browse/KYLIN-1980?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15445267#comment-15445267 ]
Zhong Yanghong commented on KYLIN-1980:
---------------------------------------
A cube based on the sample data with measure TopN is created. When do the following query,
select seller_id, sum(price) as price_sum
from kylin_sales
group by seller_id
order by price_sum
desc
limit 15
The result by kylin is shown in figure !kylin_result.png|thumbnail!
The result by hive is shown in figure !hive_result.png|thumbnail!
For seller id with 10000102, it's strange that the related result by hive is smaller than the one by kylin with TopN.
