---------------------------------------

             Summary: Ambari Web UI should validate cluster name.
                 Key: AMBARI-6453
                 URL: https://issues.apache.org/jira/browse/AMBARI-6453
             Project: Ambari
          Issue Type: Improvement
          Components: client
    Affects Versions: 1.6.1
            Reporter: Pradeep Bhadani
            Priority: Minor


Ambari Web UI should validate the Hadoop cluster name.

Best practices for choosing the cluster name is to avoid special character and white-spaces
. These validation should be there at Ambari Web UI level.

At present Ambari UI "text-box" for cluster name can accept special character like Underscore
( _ ).

If you create Cluster Name having underscore( _ ) , you cannot enable HA.

Also , we cannot change the cluster name of existing hadoop cluster.

Above ticket is OPEN.
