Description

PROBLEM: When configuring the Capacity Scheduler view the customer had to manually define the ambari server url because normally they access ambari server over SSL through an alias, which is defined in the commonName of the SSL cert.
The customer's hostname and cluster name have a - in them. This fails the regex and therefore the host can't be updated. Since the validator code is running on the server side and not in Javacript, even if we were to use the REST API to update this it would be the same one Ambari is already using so I see no workaround for this other than to directly manipulate the database.
Specifically the validation I'm talking about is here:
contrib/views/capacity-scheduler/src/main/java/org/apache/ambari/view/capacityscheduler/PropertyValidator.java
This regex needs to be relaxed, and ideally if this validation is going to be done it should be using whatever rules used in Ambari elsewhere. For example if I can create the host or cluster in Ambari to start with then such a name should never fail a validation rule anywhere else in Ambari ever for any reason.

Url like http://c1-node.local:8080/api/v1/clusters/c1 were failing because of the hyphen in the URL.
