Hi Souvik
For custom HA support, you may take a look at an example of an HA wizard and try to implement your own or tweak the existing one to make it work for your use case. All the code is under ambari-web (EmberJs). Here are the controllers and views for NN HA: https://github.com/apache/ambari/tree/trunk/ambari-web/app/controllers/main/admin/highAvailability/nameNode https://github.com/apache/ambari/tree/trunk/ambari-web/app/views/main/admin/highAvailability/nameNode I think the most of the code can be re-used as is to a great extent, possibly with a lot of component name re-naming.
