      Description

      HIVE-2989 introduces the concept of table links. In this improvement, the plan is to complete the support for dynamic table links.
      Dynamic links are a type of link where
      a) if the source of the table link adds a partition, that partition is automatically added to all tables that link to it
      b) if the source of the table link drops a partition, that partition is automatically dropped from all the tables that link to it
      c) if the source of the table link has a metadata change via:
      ALTER TABLE table CHANGE COLUMN column ...
      ALTER TABLE table ADD/REPLACE COLUMN column ...
      ALTER TABLE table_name [PARTITION partitionSpec] SET LOCATION "new location"
      the links pointing to that table will also have their metadata correspondingly changed.
