[jira] [Created] (HIVE-21029) External table replication: for existing deployments running incremental replication

anishek created HIVE-21029:
------------------------------

             Summary: External table replication: for existing deployments running incremental replication
                 Key: HIVE-21029
                 URL: https://issues.apache.org/jira/browse/HIVE-21029
             Project: Hive
          Issue Type: Bug
          Components: HiveServer2
    Affects Versions: 3.1.1, 3.1.0, 3.0.0
            Reporter: anishek
             Fix For: 4.0.0


Existing deployments using hive replication do not get external tables replicated. For such deployments to enable external table replication they will have to provide a specific switch to first bootstrap external tables as part of hive incremental replication, following which the incremental replication will take care of further changes in external tables.

The switch will be provided by a hive configuration and is to be used in 
{code} WITH {code}  clause of 
{code} REPL DUMP {code} command. 

Additionally the following hive config _hive.repl.include.external.tables_  will always have to be set to "true" in the above clause.
