-------------------------------------------

             Summary: Handling drop and rename table when links point to it
                 Key: HIVE-3097
                 URL: https://issues.apache.org/jira/browse/HIVE-3097
             Project: Hive
          Issue Type: Improvement
          Components: Query Processor
    Affects Versions: 0.10.0
            Reporter: Sambavi Muthukrishnan
            Assignee: Bhushan Mandhani


HIVE-2989 introduces the concept of table links into Hive.
In this improvement, we will continue the support for table links by handling cases where
the source of the table link is dropped/renamed.

When the source of a table link is dropped via DROP TABLE, the behavior will be that all table
links that point to it, are dropped as well.

When the source of a table link is renamed via ALTER TABLE ... RENAME ..., the behavior will
be that all table links that point to it are renamed from T@Y to T1@Y where the table T was
renamed to T1.
