---------------------------------------
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.
