---
Hi [~liyang.g...@gmail.com] & [~yimingliu], after checking the patch from
[KYLIN-3085], I found {{AutoReadWriteLock}} is introduced for {{CubeManager}}
to update cube instance data and the bugs of the copy-on-write design are
almost fixed. I agree not to merge this patch and this JIRA can be closed.
Will add one more unit test later.

Then if the job is dropped by some one, the segment will not be able to be deleted.
