JiangYang created KYLIN-4972:
--------------------------------

             Summary: Don't allow segment merge when use dict.global.SegmentAppendTrieDictBuilder to build bitmap_map measure
                 Key: KYLIN-4972
                 URL: https://issues.apache.org/jira/browse/KYLIN-4972
             Project: Kylin
          Issue Type: Bug
            Reporter: JiangYang
            Assignee: JiangYang
             Fix For: v3.1.2


When *org.apache.kylin.dict.global.SegmentAppendTrieDictBuilder* is used for bitmap count distinct measure, cube segment merge will lead to incorrect bitmap merge. Therefore, we should forbid segment merge in this case.
