There is a minor bug in "Update Cube Info" step when build a cube in
distributed env, which will make this job failed, but the next auto merge job
won't be affected and will succeed. So the cube data still is consistent and

kangkaisen commented on KYLIN-2547:
---
The issue reason is keepCubeRetention() and mergeCubeSegment() *only supports
multithreading concurrence* and doesn't support multi-process concurrence.
So, we should only allow the job server keeping the segment lock to handle the
retention check and segment auto merge.
