Sounds like this bug.  https://issues.apache.org/jira/browse/KYLIN-1934

seems like it relate to dict,I do have some dimension with dict encoding:
[cid:_Foxmail.1@e8154662-2fdc-4074-b4bc-723745b0590b]
kylin 1.5.3

some of those segments maybe empty,other not,I think this could be the cause?
any idea?
