Question-10: Which of the following Replications are supported?

  1. Replicating to and from HDP to Cloudera Manager 7.x
  2. When Kerberos authentication is used on a cluster, replication from a secure source to an insecure destination
  3. Hive replication policies managed to managed table replication.
  4. Ranger to Ranger replication
  5. None of the above

Answer: 5

Sentry to Ranger replication

You require Cloudera Manager version 6.3.1 and above to run HDFS replication policies on a Sentry-enabled source cluster and to run Hive replication policies to migrate Sentry policies in source cluster to Ranger policies in 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.

You can use the Hive replication policies to migrate the Sentry policies to Ranger policies for Hive objects and URLs. The Sentry policies are automatically converted to Ranger policies in the target cluster.

Unsupported Replication Scenarios

Versions: Replicating to and from HDP to Cloudera Manager 7.x is not supported.

Kerberos: When Kerberos authentication is used on a cluster, replication from a secure source to an insecure destination is not supported.

Hive Replication: Hive replication policies do not support managed to managed table replication. When you replicate from a CDH cluster to a CDP Private Cloud Base cluster, Replication Manager converts managed tables to external tables.

Ranger: Ranger to Ranger replication is not supported.

Apache Knox: If Cloudera Manager is configured with Knox, Replication Manager does not work.
