Date Wed, 04 Jul 2018 00:50:00 GMT
Shaofeng SHI created KYLIN-3440:

             Summary: Couldn't merge if there is an empty segment
                 Key: KYLIN-3440
             Project: Kylin
          Issue Type: Bug
          Components: Web 
    Affects Versions: v2.4.0, v2.3.1
            Reporter: Shaofeng SHI
         Attachments: 2018-07-04 上午8.42.08.png

I have a cube which has empty segment (actually the segment is not empty, just because the
job counter wasn't fetched). When I try to merge the segments, Kylin reports error, asking
me if I want to continue forcely; When click "yes", the same error be reported. From the http
request, I didn't see the "forceMergeEmptySegment" parameter was set.
{code:java} Empty cube segment found, couldn't
merge unless 'forceMergeEmptySegment' set to true: [20120101000000_20120801000000, 20120801000000_20180701000000]
