> External tables are currently mapped to managed tables on target. A lot of jobs in user
environment are dependent upon locations specified in external table definitions to run, hence,
the path for external tables on the target and on the source are expected to be the same.
An external table being loaded as a  managed table makes it difficult for failover (Controlled
Failover) / failback since there is no option of moving data from managed to external table.
So the external table replicated to target cluster needs to be kept as external table with
same location as on the source.
