Prerequisites for adding classic clusters

Make sure you verify the version requirements of your classic clusters and install or configure all of the classic cluster requirements before you try to add or register them to CDP.

Required roles

You need to have the ClassicClustersCreator role to register a classic cluster in CDP.

Check the version compatibility

Make sure that the following version requirements are met.

  • For adding HDP clusters:
    • HDP - HDP 2.6.5.50000 plus any required patch version
    • DLM Engine version - 1.7.0.0-x
    • Ambari - 2.7.3 or 2.6.2.2 or 2.6.2
  • For adding CDH clusters:
    • CDH - 5.x and 6.x
    • Cloudera Manager - 5.x and 6.x
  • For adding CDP Private Cloud Base clusters
    • CDP Private Cloud Base cluster 7.1.4 or later, and its respective Cloudera Manager version; For example, CDP Private Cloud Base cluster 7.1.6 uses Cloudera Manager 7.3.1.

Verify the required roles are assigned

  • Make sure that the user can log in as the admin user to Ambari in the HDP cluster.

  • Make sure the user can log in as the admin user to Cloudera Manager in the CDH cluster or the CDP Private Cloud Base cluster.

Install the required components (HDP only)

HDP

  • Make sure that Ambari Metrics is installed in Ambari in the HDP clusters.
  • Make sure that Ambari is configured with LDAP.
  • Make sure that Knox is installed and the default topology is configured with LDAP.
  • Make sure that there is at least one topology in the Knox setup with the same LDAP as Ambari.
  • If there are policies restricting access through Knox, make sure that Ranger policies allow communication through Knox.
  • Make sure that the cluster is configured with Kerberos.
  • Make sure that the user credential used for registering the classic cluster is a valid LDAP user with an admin role in Ambari.

CDH

  • Make sure that Metrics Server is installed in Cloudera Manager in the CDH clusters.

CDP Private Cloud Base

  • Make sure that the Metrics Server is installed in Cloudera Manager on the CDP Private Cloud Base cluster.

Open ports for CCM

If you would like to use Cluster Connectivity Manager v2 (CCMv2), ensure that outgoing traffic is allowed on the port range 6000-6049 (CCMv1) or port range 443 (CCMv2) on the legacy CDH, HDP, or CDP Private Cloud Base cluster.

After making sure that your clusters meet all the requirements, you can add your CDH, HDP, and CDP Private Cloud Base clusters to CDP.
