Lemont created KYLIN-3410:

             Summary: kylin 
                 Key: KYLIN-3410
             Project: Kylin
          Issue Type: Bug
          Components: Query Engine
    Affects Versions: v2.3.1
            Reporter: Lemont

 I set city_id , pt and periods_time to Mandatory Dimensions and My query is :

 floor((1528732800 - biz_time)*1.0/(7*86400)) pt,
 count(DISTINCT online_rider) 
 from rider
 and periods_time in (0)
 and city_id = 1
 group by floor((1528732800 - biz_time)*1.0/(7*86400))

and the error is

Caused by: java.lang.NullPointerException
 at org.apache.kylin.measure.bitmap.RoaringBitmapCounter.getMutableBitmap(

but the interesting thing is that when i set pt=from_unixtime(unix_timestamp('20180612','yyyyMMdd'),'yyyyMMdd')


the query is success.
