Designating a Replication Source

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

The Cloudera Manager Server that you are logged in to will be treated as the destination of replications setup via that Cloudera Manager. From the Admin Console of this destination Cloudera Manager, you can designate a peer Cloudera Manager Server which will be treated as a source of HDFS and Hive data for replication.

Configuring a Peer Relationship

  1. Go to the Peers page by selecting Administration > Peers. The Peers page displays. If there are no existing peers, you will see only an Add Peer button in addition to a short message. If you have existing peers, they are listed in the Peers list.
  2. Click the Add Peer button.
  3. In the Add Peer pop-up, provide a name, the URL (including the port) of the Cloudera Manager Server that will act as the source for the data to be replicated, and the login credentials for that server. Cloudera recommends that SSL be used and a warning is shown if the URL scheme is http instead of https. Once both peers have been configured to use SSL/TLS, add the remote source Cloudera Manager's SSL certificate to the local Cloudera Manager truststore, and vice versa.
  4. Click the Add Peer button in the pop-up to create the peer relationship. The peer is added to the Peers list.
  5. To test the connectivity between your Cloudera Manager Server and the peer, select Actions > Test Connectivity.

Modifying Peers

  1. Go to the Peers page by selecting Administration > Peers. The Peers page displays. If there are no existing peers, you will see only an Add Peer button in addition to a short message. If you have existing peers, they are listed in the Peers list.
  2. Choose an action and follow the procedure:
    • Edit
      1. From the Actions menu for the peer, select Edit.
      2. Make your changes.
      3. Click Update Peer to save your changes.
    • Delete - From the Actions menu for the peer, select Delete.

Configuring Peers with SAML Authentication

If your cluster uses SAML Authentication do the following before creating a peer:
  1. Create a Cloudera Manager user account that has the User Administrator or Full Administrator role.

    You can also use an existing user that has one of these roles. Since you will only use this user to create the peer relationship, you can delete the user account after adding the peer.

  2. Create or modify the peer, as described in this topic.
  3. (Optional) Delete the Cloudera Manager user account you just created.
