> The Blueprints processor currently will fail during the deployment of an HDFS NameNode
HA cluster if the following properties in "hdfs-site" are not specified in the Blueprint:
> "dfs.namenode.http-address"
> "dfs.namenode.https-address"
> "dfs.namenode.rpc-address"
> These HDFS address properties are required in a non-HA scenario, but should not be required
when an HA cluster is configured.  In the HA configuration, there are settings for each of
these address properties on a per-namenode basis (with the property names including the name
of the nameservice and namenode). 
> The Blueprint processor will currently fail to start a cluster, and throw an error back
to the cluster deployer, mentioning that these properties must be set.  This is incorrect,
since HDFS does not require these properties in an HA cluster. 
> I'm working on a fix for this, and will be submitting a patch shortly.
