> If hive.repl.enable.move.optimization is set to true, then Hive REPL LOAD avoids move
operation and copy the data files directly to target location. This is helpful for Cloud replication
where the move is non-atomic and also implemented as copy.
> Currently, if hive.strict.managed.tables is enabled at target and if migration to transactional
table is needed during REPL LOAD, then this optimization is disabled.
> Need to support it.
