[jira] [Commented] (KYLIN-2253) sql union did not remove duplicated records (distinct)

    [ https://issues.apache.org/jira/browse/KYLIN-2253?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15730754#comment-15730754 ] 

zhou degao commented on KYLIN-2253:
-----------------------------------

I got another finding:
in kylin 1.6 if i run SELECT * FROM lookup_time_by_day where the_date='2040-12-31' union all SELECT * FROM lookup_time_by_day where the_date='2040-12-31'
I got: 
2040	12/31/2040	12	31	1	Q4	h2
2040	12/31/2040	12	31	1	Q4	h2

in kylin 1.5.2 if i run the same query
I got: 
2040	12/31/2040	12	31	1	Q4	h2
which is what we want i think.
