Managing high availability

Ambari web provides a wizard-driven user experience that enables you to configure high availability of the components that support services across the stack. High availability is assured through establishing active and standby components. If an active component becomes unavailable, the standby component is available. After configuring high availability for a service, Ambari enables you to manage and disable (roll back) high availability of components in that service.
