> When deploying Ambari Blueprints with extensive configuration (i.e. those
> generated from known-working clusters) Ambari should allow for the Blueprint
> to be generalized to the extent that no hostnames/FQDNs are necessary in a
> Blueprint. This requires host group substitution across the entire Blueprint.
> A few known locations lacking this support are Knox topology.xml, host-group
> specific YARN configuration overrides, and initial HA namenode standby.
> This was also previously mentioned in the mailing list here:
