Description

In version 2.1, kylin allow hole between segment.
But currently, there is validation for delete segment.
Here is the code in CubeService:
if (!segmentName.equals(cube.getSegments().get(0).getName())
&& !segmentName.equals(cube.getSegments().get(cube.getSegments().size() - 1).getName()))

{ throw new BadRequestException(String.format(msg.getDELETE_NOT_FIRST_LAST_SEG(), segmentName)); }

Does it make sense? Should we remove the limit?
