-----------------------------------
Hi yanghong
consider using org.apache.kylin.metadata.model.TableDesc#getIdentity, it
contains db name as well. This could possibly avoid another round "duplication".
Also, before merging the patch, you have to make changes in
org.apache.kylin.engine.mr.steps.MetadataCleanupJob to reflect your changes
here.

> Currently the key for the snapshot stored in hbase metadata file is as
> follows:
> ResourceStore.SNAPSHOT_RESOURCE_ROOT + "/" + new
> File(signature.getPath()).getName() + "/" + uuid + ".snapshot"
> However, some hive tables stored in hive may organized like
> dirName/tableName/00, dirName/tableName/01.
> Based on current setting, the key will be
> ResourceStore.SNAPSHOT_RESOURCE_ROOT + "/" + 00 + "/" + uuid + ".snapshot",
> which is lack of the table name information.
