When setting up /etc/hosts, you can use what= ever domain name you would like (just pick one arbitrarily).  <= /div>
For example, host01.hadoop, host02.hadoop, e= tc., where "hadoop" is the chosen domain name.

Hi Adaryl,
 
Ambari expects FQDNs to be set on the hosts. 
On your hosts, you want to make sure that "hostname -f" retu= rns the FQDN (with the domain name, like c6401.ambari.apache.org).
 
Your /etc/hosts should look something like below (note that for each h= ost, there's the FQDN followed by the short name):
127.0.0.1   localhost localhost.localdomain localhost4 local= host4.localdomain4
::1         localhost localhos= t.localdomain localhost6 localhost6.localdomain6
192.168.64.101 c6401.ambari.apache.org c6401
192.168.64.102 c6402.ambari.apache.org c6402
192.168.64.103 c6403.ambari.apache.org c6403
 
For your future reference, you may want to ask Ambari-specific questio= ns via user@ambari.apache.org.
 
I hope this helps!
Yusaku

I’m trying to set up a Hadoop cluster but Ambari is giving me is= sues. 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 eve= n 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 itR= 17;s not a FQDN. What exactly is Ambari expecting?
