Description

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!
