Capacity is assigned to the queues as min and max percentages of the parent in the hierarchy.
The minimum capacity is the amount of resources the queue should expect to have available to it if everything is running maxed out on the cluster.
The maximum capacity is an elastic like capacity that allows queues to make use of resources which are not being used to fill minimum capacity demand in other queues.
Children Queues inherit the resources of their parent queue
Minimum User Percentage and User Limit Factor are ways to control how resources get assigned to users within the queues they are utilizing.
The Min User Percentage is a soft limit on the smallest amount of resources a single user should get access to if they are requesting it.
User Limit Factor is a way to control the max amount of resources that a single user can consume.

#Installing Ranger Admin HA via Ambari causes a full cluster outage and the ambari wizard takes full control of the restarts.
#Below are the steps to enable HA manually wiht out having to use Ambari for setup.
1. Add Ranger Admin component to another host selected for HA in the cluster using Ambari API.
curl -u username:password -H "X-Requested-by:ambari" -i -k -X POST -d '{"host_components" : [{"HostRoles":{"component_name":"RANGER_ADMIN"}}]}' http://<ambari_host>:8080/api/v1/clusters/<clustername>/hosts?Hosts/host_name=<host_where_you_need_ha_component>
Note: Ambari API command used above puts Ranger Admin component on host. To install Ranger Admin component, go to Ambari --> Ranger --> Ranger Admin Host --> Click on drop down to re-install
Warning: Do not start Ranger Admin yet.
2. Setup loadbalancer for both Ranger Admins
