> Project: Hive
> Issue Type: Bug
> Components: Metastore, Statistics
> Reporter: Chaoyu Tang
> Assignee: Chaoyu Tang
>
> Currently we simply delete the column stats after renaming a database, table,
> or partition since there was not an easy way in HMS to update the DB_NAME,
> TABLE_NAME and PARTITION_NAME in TAB_COL_STATS and PART_COL_STATS. With the
> removal of these redundant columns in these tables (HIVE-11786), we will
> still keep column stats in the operation which is not to change a column name
> or type.
