Kylin cube edit and rebuild issues

["250635732@qq.com" <25...@qq.com>]

Hi, guys,

We are wondering how kylin keep cube and cubedesc to be versionized. For example, if we modify the current cubedesc, e.g. 

adding or deleteing one dimension, and when we save the cube info the older cube would be overlapped and queries over the 

older version cube would be impossible. 

Question is : Does kylin had some strategies of versionizing the cube info ? If so, how would that be implemented ? 

Any available hints shall be appreciated. 

Best,
Sun.

The resource tool can help you manage the metadata:
https://github.com/apache/incubator-kylin/blob/master/docs/Operations/Kylin%20Metadata%20Store.md

Specifically, there's is a "remove" command (in addition to upload and
download) that let you delete a metadata file.

[dong wang <el...@gmail.com>]

also have a related question, I forgot how did I operate the cube,
currently, I always find a error in the log info:

[Thread-9]:[2015-05-08
17:36:10,714][ERROR][org.apache.kylin.cube.CubeDescManager.reloadAllCubeDesc(CubeDescManager.java:198)]
- Error
loading cube desc /cube_desc/active_user_test_1.json

actually, this one is unuseful now, therefore, do we have some safe
approach to fix and remove the error information?

AFAIK, we do not have any versioning for cube descs.
