[jira] [Created] (HIVE-17021) Support replication of concatenate operation.

Sankar Hariappan created HIVE-17021:
---------------------------------------

             Summary: Support replication of concatenate operation.
                 Key: HIVE-17021
                 URL: https://issues.apache.org/jira/browse/HIVE-17021
             Project: Hive
          Issue Type: Sub-task
          Components: Hive, repl
    Affects Versions: 2.1.0
            Reporter: Sankar Hariappan
            Assignee: Sankar Hariappan
             Fix For: 3.0.0


We need to handle cases like ALTER TABLE ... CONCATENATE that also change the files on disk, and potentially treat them similar to INSERT OVERWRITE, as it does something equivalent to a compaction.
Note that a ConditionalTask might also be fired at the end of inserts at the end of a tez task (or other exec engine) if appropriate HiveConf settings are set, to automatically do this operation - these also need to be taken care of for replication.
