[jira] [Commented] (KYLIN-3400) WipeCache and createCubeDesc causes
deadlock
[ https://issues.apache.org/jira/browse/KYLIN-3400?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16518902#comment-16518902 ]
kangkaisen commented on KYLIN-3400:
-----------------------------------
I think the root cause for this bug maybe is the metadata managers have circular dependencies. For example,
ProjectManager depend on other metadata managers and other metadata managers also depend on ProjectManager, which is easily to cause dead lock, and when we add or update a method to metadata managers , we need to think a lot.
