Migrating the nodes between clusters

Migrating the nodes between clusters

Expert Contributor

I got multiple clusters and would like to move some nodes between clusters managed by Cloudera Manager. Is there any documentation on how to move node(s) from one cluster to another? Do the nodes need to be running on the same version of CDH?

 

Thanks!

Moving a Host Between Clusters

Moving a host between clusters can be accomplished by:

  1. Decommissioning the host (see Decommissioning a Host).
  2. Removing all roles from the host (except for the Cloudera Manager management roles). See Deleting a Role Instance.
  3. Deleting the host from the cluster (see Deleting Hosts), specifically the section on removing a host from a cluster but leaving it available to Cloudera Manager.
  4. Adding the host to the new cluster (see Adding a Host to the Cluster).
  5. Adding roles to the host (optionally using one of the Host Templates associated with the new cluster). See Adding Role Instances and Working with Host Templates.
