[jira] [Created] (KYLIN-2399) CubeSegmentScanner generated inaccurate

WangSheng created KYLIN-2399:
--------------------------------

             Summary: CubeSegmentScanner generated inaccurate
                 Key: KYLIN-2399
                 URL: https://issues.apache.org/jira/browse/KYLIN-2399
             Project: Kylin
          Issue Type: Improvement
          Components: Query Engine
    Affects Versions: v1.5.4.1
            Reporter: WangSheng
            Assignee: liyang
             Fix For: Future


My project has three segment:
20160601000000_20160602000000,
20160602000000_20160603000000,
20160603000000_20160604000000

When I used filter condition like this : day>='2016-06-01' and day<'2016-06-02'
Kylin would generated three CubeSegmentScanner, and each CubeSegmentScanner's GTScanRequest are not empty!

When I changed filter condition like this : day>='2016-06-01' and day<='2016-06-02'
Kylin would also generated three CubeSegmentScanner, but the last CubeSegmentScanner's GTScanRequest is empty!
