---------------------------------------

             Summary: Incremental replication adds redundant COPY and MOVE tasks for external table events.
                 Key: HIVE-21261
                 URL: https://issues.apache.org/jira/browse/HIVE-21261
             Project: Hive
          Issue Type: Improvement
          Components: repl
    Affects Versions: 4.0.0
            Reporter: Sankar Hariappan
            Assignee: Sankar Hariappan


For external tables replication, the data gets copied as separate task based on data locations listed in _external_tables_info file in the dump. So, individual events such as ADD_PARTITION or INSERT on the external tables should avoid copying data. So, it is enough to create table/add partition DDL tasks. COPY and MOVE tasks should be skipped.
