Hive ACID table replication policies

You can create the Hive ACID table replication policies in Replication Manager to copy ACID tables between CDP Private Cloud Base clusters for backup, load balancing, and other purposes.

Hive ACID table replication policies can:
  • replicate ACID tables.
  • perform incremental replication based on metastore events.

To perform Hive ACID table replication using Replication Manager, Cloudera Manager Server must manage the target cluster. You can use the same server or a peer Cloudera Manager Server to manage the source cluster. Hive ACID table replication policies use Hive scheduler to schedule the frequency of replication policy job runs.

Hive ACID table replication policies cannot replicate data:

  • between cloud-based clusters.

  • in external tables.

  • within the same cluster.
