Description

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.
