Configuring Ranger Policy Administration High Availability

If you would like to enable high availability for the Ranger Policy Administration component, you can configure the component by following the steps listed below.

  1. Install the Ranger Admin component on the hosts you wish to use.


    Make sure you use the same configuration and policy database settings for each host, otherwise, you will be unable to configure HA for the hosts.

  2. Configure a load balancer to balance the loads among the various Ranger Admin instances and take note of the load balancer URL.


    Describing the steps you need to follow in order to install and configure a load balancer is not in the scope of this book.

  3. Update the Policy Manager external URL in all Ranger Admin clients (Ranger UserSync and Ranger plug-ins) to point to the load balancer URL.
