> Blueprints: Add support for deploying HDFS NameNode HA Clusters
> ---------------------------------------------------------------
>
> Key: AMBARI-8771
> URL: https://issues.apache.org/jira/browse/AMBARI-8771
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 1.7.0
> Reporter: Robert Nettleton
> Assignee: Robert Nettleton
> Fix For: 2.0.0
>
> Attachments: AMBARI-8771.patch.4

>
> It should be possible to deploy a cluster using Blueprints that can support
> HDFS NameNode HA.
> 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 user.
> 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.
