Adding a Hue role instance with Cloudera Manager

Roles are functions that comprise a service. Role instances must be assigned to one or more hosts. You can assign roles to hosts by using Cloudera Manager.

  1. In the Cloudera Manager Home page, select the Hue service.
  2. On the Hue service page, click the Instances tab.
  3. On the Instances tab page, click Add Role Instances on the right side of the page.
  4. On the Assign Roles page:
    1. Click Select hosts under the role names to select hosts where you want to add the role. This launches a dialog box where you can select hosts where you want to add the role.
      The wizard evaluates host hardware configurations to determine the best hosts for each role. All worker roles are automatically assigned to the same set of hosts as the HDFS DataNode. You can reassign if necessary. Specify hostnames by IP address, rack name, or by range:
      Range Definition Matching Hosts
      10.1.1.[1-4] 10.1.1.1, 10.1.1.2, 10.1.1.3, 10.1.1.4
      host[1-3].company.com host1.company.com, host2.company.com, host3.company.com
      host[07-10].company.com host07.company.com, host08.company.com, host09.company.com, host10.company.com
    2. Click OK to save your hostname selection for a role.
    3. When you are finished assigning roles to hosts, click Continue in the lower right corner of the page.
  5. Cloudera Manager automatically adds the roles and returns you to the Hue Instances tab.
