installation with Ambari

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?

When setting up /etc/hosts, you can use whatever domain name you would like (just pick one arbitrarily).
For example, host01.hadoop, host02.hadoop, etc., where "hadoop" is the chosen domain name.

This is turning into less about Ambari and more general computing. I'm trying to set up Hadoop on a home network. Not work, not on EC2; just a simple three node cluster in my personal computer lab. My machines don't belong to a domain. Everything I read says that in this situation, the computer name is the FQDN. Do I need to make a domain so my cluster will work properly?

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 (with the domain name, like c6401.ambari.apache.org).

Your /etc/hosts should look something like below (note that for each host, there's the FQDN followed by the short name):
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost 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 via user@ambari.apache.org<ma...@ambari.apache.org>.

I hope this helps!

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 (with the domain name, like c6401.ambari.apache.org).

Your /etc/hosts should look something like below (note that for each host, there's the FQDN followed by the short name):
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost 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 via user@ambari.apache.org.

I hope this helps!
Yusaku

Subject: installation with Ambari

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.
