             Summary: hostname resolution failure should also include info on what hostnames did not resolve
                 Key: AMBARI-6248
                 URL: https://issues.apache.org/jira/browse/AMBARI-6248
             Project: Ambari
          Issue Type: Task
            Reporter: Xi Wang
            Assignee: Xi Wang
            Priority: Critical


I had c6403 fail to resolve hostname c6402, which causes the hostname resolution warning. That all showed fine as expected (see attached).
But, it doesn't provide any more details. It told me c6403 had a hostname resolution failure but didn't tell me c6402 failed. If it had to resolve a lot of hosts, this might be hard to track down. I believe the API gives back the info (how many failed and which hosts they were), we can include that in the UI and report.
