CDP CLI commands for HBase replication policies

You can create, activate, or delete HBase replication policies using CDP CLI commands. Use the activate-hbase-policy, continue-hbase-setup, create-hbase-policy, delete-hbase-policy, get-cluster-config, list-paired-hbase-clusters, suspend-hbase-policy, update-hbase-policy, and verify-hbase-cluster-pair CDP CLI commands for HBase replication policies along with the existing replicationmanager CDP CLI commands.

For more information, see Creating HBase replication policy.

Fine-grained permission to access CDP Public Cloud Replication Manager

You can choose to restrict user access to view and use CDP Public Cloud Replication Manager with RBAC entitlement. To enable or disable the role-based access control (RBAC) entitlement, contact your Cloudera account team.

For more information, see Fine-grained permission to access CDP Public Cloud Replication Manager.

Replication Manager support for AWS temporary credentials (technical preview)

You can use temporary AWS credentials, through the IDBroker service, to replicate HDFS data, Hive external tables, and HBase data from 7.1.9 SP1 Kerberized CDP Private Cloud Base clusters using Cloudera Manager 7.11.3 CHF7 or higher versions to CDP Public Cloud S3 clusters. You can also use the temporary AWS credentials to replicate HDFS data from S3 buckets to 7.1.9 SP1 Kerberized CDP Private Cloud Base clusters or higher using Cloudera Manager 7.11.3 CHF7 or higher versions.

This is a technical preview feature. It is not recommended for production deployments. Cloudera recommends that you try this feature in development or test environments. To enable this feature, contact your Cloudera account team.

HBase replication policy enhancements

Specify custom username

Starting from CDP Public Cloud 7.2.18.200, you can specify a custom username in the Select Source > Export snapshot user field during the HBase replication policy creation process. The option appears after you choose the Select Source > Perform Initial Snapshot option. Replication Manager uses the specified username on the source cluster to export the initial snapshot to the target.

For more information, see Creating HBase replication policies.

HBase replication policy enhancements

Replicate data through an network load balancer (NLB)

During the HBase replication policy creation process, you can choose to specify an NLB if the source CDH 5.16.2 cluster uses the NLB to communicate with ZooKeeper and RegionServers of the destination Cloudera Manager of COD clusters.

Specify the NLB details after you enable the Select Destination > Replicate via a Network Load Balancer option during the HBase replication policy creation process.

For more information, see Support matrix for CDP Replication Manager and Creating HBase replication policies.

Specify maximum number of tables to process in parallel

You can specify the maximum number of tables to process in parallel during the initial snapshot export and import step during an HBase replication policy run. You specify the number of tables using the Initial Snapshot Settings > Maximum parallel snapshots option during the HBase replication policy creation process. If you do not enter any value, Replication Manager chooses an appropriate value, depending on the resources in the source and target cluster, to optimize the performance.
