Configuring Cloudera Manager for High Availability With a Load Balancer

This section provides an example of configuring Cloudera Manager 5 for high availability using a TCP load balancer. The procedures describe how to configure high availability using a specific, open-source load balancer. Depending on the operational requirements of your CDH deployment, you can select a different load balancer. You can use either a hardware or software load balancer, but must be capable of forwarding all Cloudera Manager ports to backing server instances. (See Ports Used by Cloudera Manager and Cloudera Navigator for more information about the ports used by Cloudera Manager.)

This topic discusses Cloudera Manager high availability in the context of active-passive configurations only; active-active configurations are currently unsupported. For more information about the differences between active-passive and active-active High Availability, see
