             Summary: [NN Federation] Incase of providing invalid Nameservice as param, then service is created with invalid endpoint url
                 Key: KNOX-1287
                 URL: https://issues.apache.org/jira/browse/KNOX-1287
             Project: Apache Knox
          Issue Type: Bug
    Affects Versions: 0.14.0
            Reporter: J.Andreina
             Fix For: 1.0.0


 Incase of providing invalid Nameservice as param, then HDFSUI,Namenode and  webhdfs service is created with invalid endpoint url

Given nameservice as "ns3" which is not available, then:

1. The "NAMENODE" service is created with endpoint url as "hdfs://ns3" which doesnt exist.
2. services like "HDFSUI" and "WEBHDFS" are created without any endpoint urls
