---------------------------------------
Summary: RENAME TABLE and RENAME PARTITION events shall be
modified as DROP+CREATE events.
Key: HIVE-16676
URL: https://issues.apache.org/jira/browse/HIVE-16676
Project: Hive
Issue Type: Sub-task
Components: repl
Affects Versions: 2.1.0
Reporter: Sankar Hariappan
Assignee: Sankar Hariappan
Currently, RENAME TABLE and RENAME PARTITION events are treated as ALTER
events.
For bootstrap dump, if the table is renamed after fetching the table names,
then new table will be missing in the dump and so the target database doesn't
have both old and new table. During incremental replication, later RENAME
events will be noop as the old table doesn't exist in target.
In order to make RENAME replication simple, it is suggested to treat RENAME as
DROP+CREATE event.
EVENT_RENAME_TABLE = EVENT_DROP_TABLE + EVENT_CREATE_TABLE.
EVENT_RENAME_PARTITION = EVENT_DROP_PARTITION + EVENT_ADD_PARTITION.
