--------------------------------
Fix Version/s: v2.1.0
> Keep UUID in metadata constant
> -------------------------------
>
> Key: KYLIN-2676
> URL: https://issues.apache.org/jira/browse/KYLIN-2676
> Project: Kylin
> Issue Type: Improvement
> Reporter: Xiaqing Wang
> Assignee: Xiaqing Wang
> Fix For: v2.1.0
>
>
> When users reset or restore the metadata, we should keep the UUID unchanged.
> Thus we can ensure the UUID as the only identifier of a metadata table.
> However, those operations that read but not alter metadata should be allowed
> to copy UUID from metadata.
> To achieve this, we add the resource filed `/UUID` into the excludes list of
> copyR and resetR method in ResourceTool.java, which makes operations
> attending to copy or reset fields skip UUID. But for those read operations,
> for example, operations relating to backup, we provide a overriding copy
> method that permit getting UUID from the metastable.
> Resolved. Please refer to:
