[ https://issues.apache.org/jira/browse/KYLIN-3501?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16732847#comment-16732847 ]

-------------------------------------
+1
org.apache.kylin.tool.CubeMetaExtractor can export single cube metadata. But I think it won't backup hive table.

> I think the performance problems is inevitable. So, I often migrate the cube from PROD ENV to DEV ENV for performance tunning.
> My steps:
> 1. find the related metadata of the cube and export the metadata;
> 2. find the related hive table and export the table data;
> 3. import the cube metadata and load the hive table data
> 4. build the cube
> How about integrating the steps into a tool?
