             Summary: Namenode dir textarea vanishes when value contains /home in path
                 Key: AMBARI-12612
                 URL: https://issues.apache.org/jira/browse/AMBARI-12612
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 2.1.0
            Reporter: Srimanth Gunturi
             Fix For: 2.1.1


Install a cluster with ZK+AMS services only. Then add HDFS service using the add-service wizard. In the configurations step, enter the value of 'NameNode directories' to '/home/foo' which should generate the validation error {{Can't start with "home(s)"}}. 

Now switch to configs of all other services and go back to HDFS configs. Now the textarea is not shown.

Workaround: Hit _Back_ followed by _Next_ to show the text-area. OR just refresh the page to repopulate the configs.
