>                 Key: AMBARI-8771
>                 URL:
>             Project: Ambari
>          Issue Type: Bug
>          Components: ambari-server
>    Affects Versions: 1.7.0
>            Reporter: Robert Nettleton
>            Assignee: Robert Nettleton
>             Fix For: 2.0.0
> It should be possible to deploy a cluster using Blueprints that can support HDFS NameNode
> Currently in Ambari, the User Interface supports adding HA support for NameNodes to a
running cluster.  
> In the Blueprint case, the HA support for NameNodes must be added at the initial cluster
deployment/startup, since Blueprints does not support an interactive model.  
> The support for NameNode HA in Ambari 2.0 should at least support an "expert mode" option,
where the user adds all of the required HA configuration to the Blueprint or cluster creation
template in order to setup an HA cluster.  In future releases, it may be possible to auto-generate
some of this configuration, in order to ease the burden of HA setup for the Blueprints/Ambari
> This work will involve changes to the Blueprint validation code, since our stacks do
not currently support HA directly.  It should be possible to deploy a NameNode HA Blueprint
without turning off Blueprint validation.
