Adding a Cluster

Cloudera Manager can manage multiple clusters. Furthermore, the clusters do not need to run the same version of CDH; you can manage both CDH3 and CDH4 clusters with Cloudera Manager.

To add a cluster with new hosts:

  1. Do one of the following:
    • On the Home page, click and selectAdd Cluster.
    • From the Services tab, select All Services. Click the Add Cluster button at the top right of the page.
    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 Install CDH on Selected Hosts 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.

To add a cluster using currently managed hosts:

Alternatively, 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. Do one of the following:
    • On the Home page, click and selectAdd Cluster.
    • From the Services tab, select All Services. Click the Add Cluster button at the top right of the page.
    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 View Currently Managed Hosts link under the Search field. This link 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.
