What's new

This section lists major features and updates for Replication Manager service.

January 2024

This release of the Replication Manager service introduces the following new features.

Replicate HBase tables in a database depending on the replication scope

During the HBase replication policy creation process, after you select the Select Source > Replicate Database, you can choose the Select Source > Replicate all user tables option to replicate all the HBase tables in the database, or choose the Select Source > Replicate only tables where replication is already enabled option to replicate the tables for which the replication scope is already set to 1. This provides a choice to replicate the required tables in a database.

The Replicate only tables where replication is already enabled option is supported only if the target cluster CDP version is CDP version 7.2.16.500 using Cloudera Manager 7.9.0-h7 or higher versions and 7.2.17.300 using Cloudera Manager 7.11.0-h3 or higher versions.

For more information, see Methods to replicate HBase data and Creating HBase replication policies.

Replicate HBase data between multiple clusters simultaneously

Starting from CDP Public Cloud version 7.2.16.500 and 7.2.17.200, you can create multiple HBase replication policies between multiple clusters to replicate HBase data.

For more information, see Replicate HBase data simultaneously between multiple clusters.

August 2023

This release of the Replication Manager service introduces the following new features.

Replicate HBase data in all the tables in a database

You can replicate HBase data (existing tables and future tables in a database) using the Select Source > Replicate Databases option during the HBase replication policy creation process. You can use this option only if the minimum target Cloudera Manager version is 7.11.0 and the minimum source cluster versions are CDH 5.16.2 (after you upgrade the source cluster Cloudera Manager), CDP Private Cloud Base 7.1.6, or COD 7.2.17.

For more information, see HBase replication policy and Creating HBase replication policies.

Provide a unique replication policy name

You must provide a unique name to the replication policy during the replication policy creation process if the Cloudera Manager API version is 51 or higher.

For other Cloudera Manager API versions, you can continue to use an existing replication policy with an empty name. However, if you edit the replication policy and provide a name for the replication policy, ensure that the name conforms to the validation rules.

For more information, see Managing HDFS replication policy, Managing Hive replication policy, or Managing HBase replication policy.

Load replication policies and their job history on the Replication Policies page

You can choose one of the following options to Load policies faster by delaying to load their job history:

  • Delay loading job history when history is too long
  • Always load job history
  • Never load job history

By default, the replication policies are loaded only partially on the Replication Policies page, therefore the page might display incomplete statistics about a job status and replication policies with failed jobs might take a longer time to load. You can change the behavior depending on your requirements.

For more information, see Replication Policies page

June 2023

This release of the Replication Manager service introduces the following new features.

HBase replication policy enhancements

You can view the HBase RegionServer metrics for a specific replication peer in Replication Manager. You can use these metrics to monitor HBase replication jobs and to find and diagnose issues with the HBase replication peer.

For more information, see Graphical representation of HBase RegionServer replication peer metrics

CDP CLI commands for Replication Manager

You can collect and download the diagnostic bundle, add ABFS and AWS cloud credentials to use in Replication Manager and delete credentials using CDP CLI commands.

For more information, see Adding cloud credentials in Replication Manager using CDP CLI.
