[jira] [Commented] (KYLIN-1653) Cube metadata lost
[ https://issues.apache.org/jira/browse/KYLIN-1653?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15272055#comment-15272055 ]
Xingxing Di commented on KYLIN-1653:
------------------------------------
[~Shaofengshi] It seems like https://issues.apache.org/jira/browse/KYLIN-1536 , but this time we didnot change any tables or colunm name. Can you give me some hints?
Here is an another question , I see the restore metadata steping is : backup -> reset -> restore , when i reset the whole metadata will kylin working all right ? Is there a way to backup project1 -> reset project1 -> restore project1 , this looks less risk for me.
And also when i try to backup metadata i got an exception , so i can not backup the whole metadata :
