Subject duplicate host cleanup
Date Fri, 18 Dec 2015 13:15:25 GMT
I just upgraded to Ambari 2.0 on a cluster and ran into a problem with duplicate host definitions.
Somehow, some of the cluster nodes were registered twice with different FQDNs:

    node1.mycompany.com <http://node1.mycompany.com/>
    node1.foo.mycompany.com <http://node1.foo.mycompany.com/>

The correct name is the first one, but if I look at that host in the Ambari Host page,
the summary section is showing the second one. It appears this is causing the Ambari server
to fail to detected the heartbeat. 

How can I clean this up?
