If you want to enable HA for different services (Fir example "Enable NameNode HA") then in that case you can try the following:

 Ambaru UI --> HDFS --> "Service Actions" (Drop Down) --> "Enable Name Node HA"

Please See: https://docs.hortonworks.com/HDPDocuments/Ambari-2.4.1.0/bk_ambari-user-guide/content/how_to_configu...

Similarly, you can enable the HA for other services as well like "Enable ResourceManager HA")

https://docs.hortonworks.com/HDPDocuments/Ambari-2.4.0.1/bk_ambari-user-guide/content/how_to_configu...

NOTE: Following Information is regarding Enabling HA for Ambari Itself. Unfortunately currently there is no HA feature available for Ambari yet. However you can refer to the following JIRAs where the discussion is going on in this regard:

https://issues.apache.org/jira/browse/AMBARI-17126

The HA Guide covers this, and yes Ambari can be used to install, configure, and manage the services.

Re: Deploy HA Multinode Cluster using Ambari

Thanks for your reply. However, I did not see High Availability option in Ambari Installation link. I can install and manage the cluster but I want to install High Available cluster through ambari.
