             Summary: Real-time OLAP may return incorrect result for some query without group by
                 Key: KYLIN-4276
                 URL: https://issues.apache.org/jira/browse/KYLIN-4276
             Project: Kylin
          Issue Type: Bug
          Components: Real-time Streaming
    Affects Versions: v3.0.0-beta
            Reporter: Yaqian Zhang
             Fix For: Future
         Attachments: image-2019-12-02-17-01-45-838.png, image-2019-12-02-17-02-43-762.png, image-2019-12-02-17-05-19-167.png

Query 1:

!image-2019-12-02-17-01-45-838.png|width=500,height=336!

Query 2:

!image-2019-12-02-17-02-43-762.png|width=503,height=342!

The result of Query1 and Query2 should be equal, but it's not. Obviously, Query2's result is incorrect.

If there have 'group by' in SQL, the result will be correct.
