Introduction to Replication Manager

Replication Manager is a service in CDP Private Cloud Data Services. You can use this service to copy and migrate HDFS data, Hive external tables, and Ozone data between CDP Private Cloud Base 7.1.8 or higher clusters using Cloudera Manager version 7.7.3 or higher.

The following support matrix table lists the lowest supported Cloudera Manager version, Cloudera Runtime version, clusters, and supported services for Replication Manager:


Source cluster	Lowest supported source Cloudera Manager version	Lowest supported source Cloudera Runtime version	Destination cluster	Supported services on Replication Manager
CDP Private Cloud Base	7.7.3	7.1.8	CDP Private Cloud Base	HDFS, external Hive tables, Ozone data

You can access the Replication Manager service on the CDP Private Cloud Data Services web interface. To replicate data between clusters, add the source and destination clusters on the Management Console > Clusters page, and then create HDFS and Hive replication policies in Replication Manager. The Replication Policies page shows the progress and status of replication policy jobs.

The Replication Manager supports the following functionalities:

HDFS replication policies

These policies replicate files or directories in HDFS.

Some use cases to use these replication policies are to:

replicate required data to another cluster to run load-intensive workflows on it which optimizes the primary cluster performance.
deploy a complete backup-restore solution for your enterprise.

Hive replication policies

These policies replicate Hive metadata and Hive external tables.

Some use cases where you can use these replication policies are to:

backup legacy data for future use or archive cold data.
replicate or move data to cloud clusters to run analytics.

Ozone replication policies

These policies replicate Ozone data.

Some use cases where you can use these replication policies are to:

replicate or migrate the required Ozone data to another cluster to run load-intensive workloads.
back up data.

You can monitor the replication policies and its progress on the Overview page and the other pages of Replication Manager. You can also monitor the statistics related to each replication policy on the CDP Private Cloud Data Services > Management Console > Dashboard > Monitoring Dashboard page.
