Note: If your cluster uses SAML Authentication, see Configuring Peers with SAML Authentication before configuring a peer.

1. Go to the Peers page by selecting Backup > Peers. If there are no existing peers, you will see only an Add Peer button in addition to a short message. If peers already exist, they display in the Peers list.
2. Click the Add Peer button.
3. In the Add Peer dialog box, provide a name, the URL (including the port) of the Cloudera Manager Server source for the data to be replicated, and the login credentials for that server.
     Important: The role assigned to the login on the source server must be either a User Administrator or a Full Administrator.
   Cloudera recommends that TLS/SSL be used. A warning is shown if the URL scheme is http instead of https. After configuring both peers to use TLS/SSL, add the remote source Cloudera Manager TLS/SSL certificate to the local Cloudera Manager truststore, and vice versa. See Configuring TLS Encryption for Cloudera Manager.
4. Click the Add Peer button in the dialog box to create the peer relationship.

   The peer is added to the Peers list. Cloudera Manager automatically tests the connection between the Cloudera Manager Server and the peer. You can also click Test Connectivity to test the connection. Test Connectivity also tests the Kerberos configuration for the clusters. For more information about this part of the test, see Kerberos Connectivity Test.

1. Go to the Peers page by selecting Backup > Peers. If there are no existing peers, you will see only an Add Peer button in addition to a short message. If peers already exist, they display in the Peers list.
2. Do one of the following:

     1. In the row for the peer, select Edit.
     2. Make your changes.
     3. Click Update Peer to save your changes.

Minimum Required Role: User Administrator (also provided by Full Administrator)

To configure Amazon S3 as a source or destination for HDFS or Hive/Impala replication, you configure AWS Credentials that specify the type of authentication to use, the Access Key ID, and Secret Key. See How to Configure AWS Credentials.

After adding the AWS credentials, you can click the Replication Schedules link to define a replication schedule. See HDFS Replication or Hive/Impala Replication for details about creating replication schedules. You can also click Close and create the replication schedules later. Select the AWS Credentials account in the Source or Destination drop-down lists when creating the schedules.
