--------------------------------
Summary: Renaming tables leaves stat store in stale state (was: Renaming
tables leaves stat store )
> Renaming tables leaves stat store in stale state
> ------------------------------------------------
>
> Key: HIVE-8734
> 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.
