[Puppet Users] Could not find default node or by name with 'ip-10-195-207-236.ec2.internal, ip-10-195-207-236.ec2, ip-10-195-207-236' on node ip-10-195-207-236.ec2.internal

Hi,

I am new to puppet. I have configured puppet master and agent.

1. Executed this "*puppetca --sign ip-10-194-18-145.ec2.internal*" command
in puppet master instance. It returns an output like
* notice: Signed certificate request for ip-10-194-18-145.ec2.internal*
* notice: Removing file Puppet::SSL::CertificateRequest
ip-10-194-18-145.ec2.internal at
'/var/lib/puppet/ssl/ca/requests/ip-10-194-18-145.ec2.internal.pem'*
* *Is there any issue with this error ?
2. Created one site.pp file in *puppet master /etc/puppet/manifests* folder
with below content.
node 'client' {
file { "/root/files/test":
source => "puppet:///files/test"
}
}
3 Added below content in *puppet master /etc/puppet/fileserver.conf*
path /etc/puppet/files
allow *.puppet.com
allow *.internal
4 When I am trying to execute command "*puppet apply site.pp*" in manifests
folder, I am getting an error message like below.
*Could not find default node or by name with
'ip-10-195-207-236.ec2.internal, ip-10-195-207-236.ec2, ip-10-195-207-236'
on node ip-10-195-207-236.ec2.internal*

I am trying to resolve this issue such a long time.Can any one help me to
resolve this issue as early possible?,

Thanks in advance.

Krishna Bhaskar.
