> The main problem is that while hostnames are only stored in the Ambari DB in lowercase letters, it is still possible for a user to specify a host with capital letters or mixed case letters in the Cluster Creation Template (submitted during a cluster deployment).
> The solution would be to convert the hostnames specified in the Cluster Creation template at deployment time to lower case, and use only lower-case hostnames in Blueprints generally (as in the rest of Ambari). This would mean that all hostnames assumed to be lower-case internally.
