Moving a Host Between Clusters

To move a host between clusters, you must first decommission the host, remove roles from the host, and complete other tasks.

  1. Decommission the host.
  2. Remove all roles from the host (except for the Cloudera Manager management roles).
  3. Remove the host from the cluster but leave it available to Cloudera Manager.
  4. Add the host to the new cluster.
  5. Add roles to the host (optionally using one of the host templates associated with the new cluster).
