Description

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.
