Adding a load balancer

Cloudera recommends you to configure load balancers for Hue to improve performance or if you have more than 10 concurrent users, and access Hue through the Hue load balancer port (8889).

  1. Log into Cloudera Manager as an Administrator.
  2. Go to Clusters > Hue service.
  3. Click Actions and select Add Role Instances.
    The Add Role Instances wizard is displayed.
  4. On the Assign Roles page, click Select hosts for Load Balancer.
    Select a host and click OK.
  5. [Optional] Add 2 additional Hue servers (for a total of 3) to boost performance:
    1. Click Select hosts for Hue Server.
    2. Select a host and click OK > Continue.
  6. Click Select Hosts for Kerberos Ticket Renewer if running Kerberos and select each host that you selected earlier.
    Every Hue host must have a Renewer.
  7. Click Continue.
    The newly added hosts are displayed on the Instances tab.
  8. Select all the newly added hosts.
  9. Click Actions for Selected and select Start.
  10. Restart the Hue service.
