> 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.
