> *Requirements:*
> Hive2 supports replication of managed tables. But in Hive3 with hive.strict.managed.tables=true,
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 incremental phases and convert
the tables accordingly.
