>                 URL: https://issues.apache.org/jira/browse/HIVE-8734
>             Project: Hive
>          Issue Type: Bug
>          Components: Metastore
>            Reporter: Ryan Pridgeon
>
> Renaming tables does not alter the data stored in the TAB_COL_STATS. So if a user renames table1 to table2 they will also need to re-compute statistics against this table.
> This is an inconvenience and puts the metastore in an inconsistent state. It neither drops or updates TAB_COL_STATS.TABLE_NAME. So you will have an entry for both the old table name and the new table name.
> This lingering data is also inherited by any table that assumes the previously used table name.
