datanode is starting in only one system
I have setup hadoop cluster environment here.
I've setup slaves file here and replication factor as 3 at here.
When I start the hadoop cluster using bin/start-dfs.sh, only one datanode starts either at datanode1.com or datanode2.com.
Since the replication factor is 3, I'm expecting datanode to start at all the nodes that I configured in slaves file.
Any idea why datanode is running only in one node.

You only have two datanodes, so it might not let you have 3 replicas, and I would really suggest using Ambari to provision all the machines. You can refer to the Hortonworks documentation for all the steps (or even use Hortonworks Ansible playbooks in your Vagrantfile)
