             Summary: Add Service Wizard: disable Deploy button after click 
(after Kerberos enabling)
                 Key: AMBARI-11834
                 URL: https://issues.apache.org/jira/browse/AMBARI-11834
             Project: Ambari
          Issue Type: Bug
          Components: ambari-web
    Affects Versions: 2.1.0
            Reporter: Aleksandr Kovalenko
            Assignee: Aleksandr Kovalenko
            Priority: Critical
             Fix For: 2.1.0


After enabling kerberos, when user opens Add Service Wizard and clicks Deploy 
button, request to validate kerberos credentials is sended. On my cluster this 
request took a while (~30 secs), and while UI was waiting for response I was 
able to click Deploy several times more (there were no spinner or button 
disabling) and returned back by wizard steps. And then after about 30 secs a 
lot of windows to input kerberos credentials appeared (as much as much times 
deploy button was clicked).
