Subject Re: Need pointers to build HA capabilty for a custom Stack in Ambari
Date Thu, 19 Jan 2017 06:21:02 GMT
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.


Regards
Matt
