Support matrix for Replication Manager on CDP Private Cloud Base

Replicate data from CDH and CDP Private Cloud Base source clusters

The following table lists the source and destination clusters, lowest supported versions of Cloudera Manager, and the services that are available for each supported cloud provider for CDH source clusters:

Replicate HDFS and Hive data to and from cloud storage

Starting in Cloudera Manager 6.1.0, Replication Manager ignores Hive tables backed by Kudu during replication. The change does not affect functionality since Replication Manager does not support tables backed by Kudu. This change was made to guard against data loss due to how the Hive Metastore, Impala, and Kudu interact.

Supported replication scenarios

Sentry-related replication

To perform Sentry to Ranger replication using HDFS and Hive external table replication policies, you must have installed Cloudera Manager version 6.3.1 and higher on the source cluster and Cloudera Manager version 7.1.1 and higher on the target cluster.

When the source cluster is Sentry-enabled and you want to run HDFS replication policies, use the hdfs user to run the replication policy. The replication policy copies the permissions of replicated files and tables to the target cluster. To use any other user account, make sure that you configure the user account to bypass Sentry ACLs during replication.

When you create a Hive external table replication policy, choose the appropriate options to ensure that the Sentry permissions are migrated to Ranger permissions. The Replication Manager uses the authzmigrator tool to move data from Sentry to Ranger during Hive external table replication.

Kerberos

Replication Manager supports the following replication scenarios when Kerberos authentication is used on a cluster:

• Secure source to a secure destination.
• Insecure source to an insecure destination.
• Insecure source to a secure destination. The following requirements must be met for this scenario:
  • When a destination cluster has multiple source clusters, all the source clusters must either be secure or insecure. Replication Manager does not support a mix of secure and insecure source clusters.
  • The destination cluster must run Cloudera Manager 7.x or higher.
  • The source cluster must run a compatible Cloudera Manager version.
  • This replication scenario requires additional configuration. For more information, see Replicating from unsecure to secure clusters.

Transport Layer Security (TLS)

You can use TLS with Replication Manager. Additionally, Replication Manager supports replication scenarios where TLS is enabled for non-Hadoop services (Hive/Impala) and TLS is disabled Hadoop services (such as HDFS,YARN, and MapReduce).

Replicate data from HDP 2 and HDP 3 source clusters

Replicating to and from HDP to Cloudera Manager 7.x is not supported by Replication Manager. However, you can replicate data using other methods. The following table lists the methods and the supported data replications to CDP Private Cloud Base clusters that are supported:
