Appendix 
 Before you create replication policies, you must register the Amazon S3 or Azure cloud
        credentials to use as cloud storage in Cloudera Replication Manager , and register the
        on-premises clusters (CDH or Cloudera Base on premises ) as
        classic clusters in the Management Console.
        
Support matrix for Cloudera 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, Cloudera Base on premises  clusters, HDP clusters) and Cloudera         on cloud (Amazon S3 (AWS), Microsoft Azure ADLS Gen2 (ABFS), and Google Cloud Platform         (GCP)) clusters. Replication Manager from HDP clusters to Cloudera Public Cloud Azure is a         beta feature and is not available for general use.Cloud credentials to use in Cloudera 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 Cloudera Replication Manager  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.
