Sankar Hariappan updated HIVE-21043:
------------------------------------
Description:
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.
