Hi Adaryl,
 
Ambari expects FQDNs to be set on the hosts. 
On your hosts, you want to make sure that "hostname -f" returns the = FQDN=20 (with the domain name, like c6401.ambari.apache.org).
 
Your /etc/hosts should look something like below (note that for = each host,=20 there's the FQDN followed by the short name):
127.0.0.1   localhost localhost.localdomain localhost4=20 localhost4.localdomain4
::1         localhost=20 localhost.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 = questions=20 via user@ambari.apache.org.
 
I hope this helps!
Yusaku
