>                 Key: AMBARI-13514
>                 URL: https://issues.apache.org/jira/browse/AMBARI-13514
>             Project: Ambari
>          Issue Type: Bug
>          Components: ambari-web
>    Affects Versions: 2.1.0
>            Reporter: Sangeeta Ravindran
>            Assignee: Sangeeta Ravindran
>
> Reproduction Steps: 
> 1.Select one or more services and click on "Deploy" button. While deploy is running, kill the browser.
> 2. Restart web browser and login to ambari-server. The UI will go back to the service deploy wizard review page.
> 3. Click on "Deploy" again and you will get an error indicating that you are trying to add a service that is already installed.
> for e.g.
> org.apache.ambari.server.controller.spi.ResourceAlreadyExistsException: Attempted to create a host_component which already exists: [clusterName=hdpcluster, hostName=myhost.mydomain.com componentName=HDFS_CLIENT]
> This happens because the services have now either already been deployed or are in the middle of deploying. 
> The only way to recover is to exit out of the wizard by clicking on the X at the right hand top edge.
> Expected results: 
> Ambari should either retrieve the status of the deploy wizard to reflect the actual state of deploy, or go back to the dash board if browser session is lost.
