Hive replication policies

Hive metadata replication involves multiple entities. Replication Manager supports replication of external tables in Hive. Hive supports replication of external tables to the target cluster and it retains all the properties of external tables. The data files permission and ownership are preserved so that the relevant external processes can continue to write in it even after failover.

Replication Manager supports replication of the Hive database from a cluster with underlying HDFS to another cluster with cloud storage. It uses push-based replication, with the replication job running on the cluster with HDFS. For information about Hive cloud replication, see Hive cloud replication
