Shaofeng SHI commented on KYLIN-1653:
-------------------------------------
If this record doesn't exist in your hbase metadata table, then it is deleted.
Please try to recover from history backups;
Usually restore metadata only need "backup" -> "restore"; The "reset" step is
not required; it will delete all resources in the metastore, so please use it
cautiously.
Restore a project scope resource is not supportted; but you can only pick up
the resources that you want to restore:
1. make an empty local folder
2. pick up and copy the resources that you want to recover to this new folder;
3. run restore from this local folder; only the resources that exists in this
folder will be uploaded; The one that you didn't pick will not be touched in
metadata table.
I guess your error was just caused that you run a "reset" before restore; the
restored version doesn't have the "flw_topic_supper.json" so caused data loss.
