Before you create replication policies, you must register the Amazon S3 or Azure
cloud credentials to use as cloud storage in CDP Public Cloud Replication Manager, and
register the on-premises clusters (CDH or CDP Private Cloud Base) as classic clusters in the
Management Console. You can also configure an SSL/TLS certificate exchange between two
Cloudera Manager instances that manage source and target cluster respectively to replicate
Support matrix for CDP Public Cloud Replication Manager You can use Replication Manager or other alternate replication methods to replicate HDFS, Hive external tables, and HBase data between on-premises clusters (CDH clusters, CDP Private Cloud Base clusters, HDP clusters) and CDP Public Cloud (Amazon S3 and Microsoft Azure ADLS Gen2 (ABFS)) clusters. Replication Manager from HDP clusters to CDP Public Cloud Azure is a beta feature and is not available for general use. Verify cluster requirements for replication policies You must complete the prerequisites before you create a replication policy in CDP Public Cloud Replication Manager. Working with cloud credentials in CDP Public Cloud Replication Manager The Cloud Credentials page shows the registered cloud credentials for Replication Manager. To replicate data to a storage cloud account, you must register the cloud credentials, so that the Replication Manager can access your cloud account. The supported cloud storage accounts are Amazon S3 and Azure Blob Filesystem (ABFS). On the Cloud Credentials page, you can add, update, or delete cloud credentials. Before you register an Amazon S3 cloud account, ensure the cloud bucket requirements are met. Before you add Azure Cloud Credentials in Cloudera Manager, ensure the Blob container requirements are met. Ports for Replication Manager on CDP Public Cloud Before you create replication policies, you must ensure that the required ports are open and available for data replication. You can verify the mandatory ports using the Replication Manager network security diagram. Configuring SSL/TLS certificate exchange between two Cloudera Manager instances The Replication Manager configures replication peers between two clusters before running the replication job. You can manually set up an SSL/TLS certificate exchange between two Cloudera Manager instances that manage source and target cluster respectively. Replication Manager uses this information to set up the peers for secure data replication.
