I’m trying to set up a Hadoop cluster but Ambari is giving me issues. At the screen where it ask me to confirm host, I get: 1. Warning that I’m not inputting a fully qualified domain name. 2. The host that the Ambari instance is actually sitting on is not even registering.
When run hostname –fqdn I get just the name of my machine. I put that into the screen asking for FQDNs and I just get a warning that it’s not a FQDN. What exactly is Ambari expecting? B.
