----------------------------------

             Summary: Usability: Ensure that hostname (fqdn) and reverse lookup resolve to
the same name - this host checkup should be done for server and agent hosts
                 Key: AMBARI-5809
                 URL: https://issues.apache.org/jira/browse/AMBARI-5809
             Project: Ambari
          Issue Type: Bug
          Components: agent
    Affects Versions: 1.6.0
            Reporter: Dmytro Sen
            Assignee: Dmytro Sen
             Fix For: 1.6.1


While debugging a setup it was noticed that the hostname and reverse lookup did not resolve
to the same host name. This resulted in some weird behavior wrt. agent registration - agent
seems to re-register every few heartbeats. Ambari should perform a host check (for both the
server host and agent hosts) and report if there is a discrepancy in the host name and reverse
lookup.
