Zhong Yanghong commented on KYLIN-2986:
---------------------------------------

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.
