Hive replication concepts

DLM supports Hive replication.

Hive replication bootstrap
DLM allows you to replicate Hive databases from a source cluster to a target location on a destination cluster.
Replication differences between HDP 2.6.5 to 3.x
In HDP 2.6.5 version, managed tables are managed by Hive.
Non-support of replication of Hive-Managed tables written by Spark applications.
DLM Hive replication for Managed tables relies on replication events being published by Hive in Hive Metastore for every change that is made by Hive.
On-premise to on-premise replication in HIVE
Before you can begin replicating data using clusters on Hive, you must make sure that there are at least a couple of clusters that are registered in your DLM App instance. The replication load happens on the target cluster.
