Hive2 supports replication of managed tables. But in Hive3, some of these managed tables are converted to ACID or MM tables. Also, some of them are converted to external tables based on below rules.
- Avro format with external schema, Storage handlers, List bucketed tabled are converted to external tables.
- Location not owned by "hive" user are converted to external table.
- Hive owned ORC format are converted to full ACID transactional table.
- Hive owned Non-ORC format are converted to MM transactional table.
REPL LOAD should apply these rules during bootstrap and convert the tables accordingly.
