When customer tries to access Ambari Blueprint:
{code:java}
http://Ambarihost:8080/api/v1/clusters/TEST?format=blueprint
They see below error message web UI:
{ "status": 500, "message": "Server Error" }
{code}
7 Aug 2017 22:14:06,516 ERROR ambari-client-thread-214895 ContainerResponse:419

{code}
Customer has setup a configuration for remote servers which are HA in their
configs.
They started seeing this after making those changes.

Basically dfs.ha.namenodes.NNSERVICE value is not defined and it errors out.
