Centos 6.3 6 node physical install fail

Hi I am trying to install a 6 node physical cluster using Ambari. We are getting the below error message in the log. We have a working 10 node cluster on VM’s and followed the ambari install guide. The install fails right at the registering hosts phase. This is on centos6.3.

STDOUT
Error in PREIN scriptlet in rpm package ambari-agent-1.2.1.2-1.x86_64
sed: can’t read /etc/ambari-agent/conf/ambari-agent.ini: No such file or directory
/bin/sh: /usr/sbin/ambari-agent: No such file or directory
python: can’t open file ‘/usr/lib/python2.6/site-packages/ambari_agent/machine.py’: [Errno 2] No such file or directory

Hi Jason,

Is passwordless ssh for root set up from the machine your running ambari on to all other nodes in the cluster?

Thanks,
Ted.

i removed the hostnames from the log.

Below is from the logs. It almost looks like a problem with the ambari-agent rpm. I have tried installing the ambari-agent manually as well and it fails. The hosts file for all hosts has the fqdn of all hosts. We have also disabled selinux & iptables. Thanks for your help!

This is out of the yum.log

Hi Jason,

Looks like Ambari agent did not install properly. Can you please check yum log and server log to see if you can get more information on what went wrong?

Thanks,
Seth
