Hi Bin,
Apache projects are using JIRA to track all tasks/bugs; The entry page is https://issues.apache.org/jira/secure/Dashboard.jspa, you need firstly create an account, then you will be able to create. Selecting KYLIN as the project name, and then enter the description and other fields. You can find a sample like https://issues.apache.org/jira/browse/KYLIN-1513

Hi Bin,
It might be a bug in sql parse/optimization, would you mind to create a JIRA for the issue you found? Many thanks!

Which SQL in kylin returns a different result by comparing to hive? sql2, or both?
2016-03-24 11:53 GMT+08:00 Bin.Li <bi...@qq.com>:
hello,
The sql is(sql1):
select channel_id,count(*) as shopper from (select shopper_id, channel_id, count(*) from ods.ods_mobile_api where "DAY" = '20160315'group by shopper_id,channel_id) as t group by channel_id order by shopper desc ;
This should be equal to(sql2):select channel_id, count(distinct shopper_id) as shopper from ods_mobile_api where day = '20160315' group by channel_id order by shopper desc;
And sql1, sql2 do can get the same results in hive, but different results between hive & kylin.What the problem is ??
Many tks!!
