Configuring a peer

Before you replicate data from source cluster to destination cluster, you must connect the Cloudera Manager with the peer and then test the connectivity.

If your cluster uses SAML Authentication, see Configuring peers with SAML authentication before configuring a peer.

  1. Go to the Cloudera Manager > Replication > Peers page.
    If there are no existing peers, Add Peer appears along with a short message. If peers already exist, they appear in the Peers list.
  2. Click Add Peer.
  3. In the Add Peer dialog box, provide a name, the peer URL (including the port) of the Cloudera Manager Server source for the data to be replicated, and the login credentials for that server.
    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.
  4. Click Add 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.
