Adding and Deleting Clusters

Required Role:

Cloudera Manager can manage multiple clusters. Furthermore, the clusters do not need to run the same version of CDH; you can manage both CDH 4 and CDH 5 clusters with Cloudera Manager.

Adding a Cluster

Action Procedure
New Hosts
  1. On the Home page, click and select Add Cluster. This begins the Installation Wizard, just as if you were installing a cluster for the first time. (See the Cloudera Manager Installation Guide for detailed instructions. )
  2. To find new hosts, not currently managed by Cloudera Manager, where you want to install CDH, enter the host names or IP addresses, and click Search. Cloudera Manager lists the hosts you can use to configure a new cluster. Managed hosts that already have services installed will not be selectable.
  3. Click Continue to install the new cluster. At this point the installation continues through the wizard the same as it did when you installed your first cluster. You will be asked to select the version of CDH to install, which services you want and so on, just as previously.
  4. Restart the Reports Manager role.
Managed Hosts You may have hosts that are already "managed" but are not part of a cluster. You can have managed hosts that are not part of a cluster when you have added hosts to Cloudera Manager either through the Add Host wizard, or by manually installing the Cloudera Manager agent onto hosts where you have not install any other services. This will also be the case if you remove all services from a host so that it no longer is part of a cluster.
  1. On the Home page, click and select Add Cluster. This begins the Installation Wizard, just as if you were installing a cluster for the first time. (See the Cloudera Manager Installation Guide for detailed instructions. )
  2. To see the list of the currently managed hosts, click the Currently Managed Hosts tab. This tab does not appear if you have no currently managed hosts that are not part of a cluster.
  3. To perform the installation, click Continue. Instead of searching for hosts, this will attempt to install onto any hosts managed by Cloudera Manager that are not already part of a cluster. It will proceed with the installation wizard as for a new cluster installation.
  4. Restart the Reports Manager role.

Deleting a Cluster

  1. Stop the cluster.
  2. On the Home page, click to the right of the cluster name and select Delete.
