> 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.
