Lemont created KYLIN-3405:

             Summary: kylin mandatory dimension
                 Key: KYLIN-3405
                 URL: https://issues.apache.org/jira/browse/KYLIN-3405
             Project: Kylin
          Issue Type: Bug
            Reporter: Lemont

I created a simple cube on kylin 2.3.1,the table has three 
dimensions:pt,biz_time and periods_time ,one measure
Something  trouble me is that when i set  biz_time to the mandatory 
dimension,the sql will execute fail.
The sql is :
select floor((1524931200 - biz_time)/(30*86400)), count(DISTINCT online_rider) 
  from rider_view where pt = '20180530' and periods_time in(0) and biz_time 
  group by floor((1524931200 - biz_time)*1.0/(30*86400)) .
The error is :
null while executing sql.
But when I remove the condition of periods_time in(0) or floor function the sql 
will execute success.
I don't  know what's the relationship between the two.
