------------------------------------
Summary: Ambari should apply host group substitution to entire
Blueprint
Key: AMBARI-15625
URL: https://issues.apache.org/jira/browse/AMBARI-15625
Project: Ambari
Issue Type: Improvement
Components: blueprints
Affects Versions: 2.2.1
Reporter: Kyle R Dunn
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:
