Hello,
I am a newbie to horton and ambari. I am trying to make a 2 node hadoop cluster with physical server.
I am thinking of using Ambari to do provisioning. However since i only have 2 nodes, can i use Ambari server and ambari-agent on same node?
Right now if i do that, ambari-agent fails to startup and gives java unknown host exception . when i used FQDN
Thanks

Yes thats possible and necessary if you want to add services to your Ambari-server node.
How does your Ambari Agent configuration look like?
Make sure you have prepared the environment according to http://docs.hortonworks.com/HDPDocuments/Ambari-2.1.2.1/bk_Installing_HDP_AMB/content/_prepare_the_e..., especially DNS settings.
