[jira] [Commented] (KYLIN-2180) Add project config and make config priority become "cube > project > server"

    [ https://issues.apache.org/jira/browse/KYLIN-2180?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15662705#comment-15662705 ] 

kangkaisen commented on KYLIN-2180:
-----------------------------------

This is my solution:
Firstly, support to add project config in web UI, web API and project metadata. I will make the project metadata is forward compatible.

Secondly, update the {{KylinConfigExt}} . 

Finally, when use the {{cube.getConfig()}} to get the property, the property will get from the config of cube, the config of project and  the config of server in turn.

> There are cases we want to override global kylin.properties in the scope of a project. E.g. the queue name of Hadoop job.
> Finally, the config priority for Kylin should be "cube > project > server". I think which is reasonable.
