Review request for Ambari and Andrew Onischuk.


Bugs: AMBARI-5809
    https://issues.apache.org/jira/browse/AMBARI-5809


Repository: ambari


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.
