[jira] [Created] (KYLIN-1344) Bitmap measure defined after TopN measure can cause merge to fail

liyang created KYLIN-1344:
-----------------------------

             Summary: Bitmap measure defined after TopN measure can cause merge to fail
                 Key: KYLIN-1344
                 URL: https://issues.apache.org/jira/browse/KYLIN-1344
             Project: Kylin
          Issue Type: Bug
    Affects Versions: v2.1
            Reporter: liyang


When the new Bitmap measure is defined after a TopN measure, the build fails inside CuboidReducer. Yerui troubleshoot to the point that the error might be in MergeCuboidMapper when it re-calculcates the TopN measure.
