Attachment: (was: AMBARI-15184.patch)
> Host with uppercased symbols was not registered during deploy via blueprints
> ----------------------------------------------------------------------------
>
> Key: AMBARI-15184
> URL: https://issues.apache.org/jira/browse/AMBARI-15184
> Project: Ambari
> Issue Type: Bug
> Components: ambari-server
> Affects Versions: 2.2.1
> Reporter: Sandor Magyari
> Assignee: Sandor Magyari
> Priority: Critical
> Fix For: 2.2.2
>
>
> 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.
