> Host registration commonly fails when Agent machine can't make it back to Server (results in failed host register because Server never sees host register).
> When using SSH to register hosts, Ambari server should confirm on the ambari agent host that it can reach the ambari server (check the web port of ambari server). If it can reach ambari server, then proceed with bootstrap process. If host cannot reach the ambari server, bail, do not start agent bootstraping and provide a message to the user "Host registration aborted. Ambari Agent host cannot reach Ambari Server. Please check the network connectivity between the Ambari Agent host and the Ambari Server"
> Other scenarios to consider:
> 1) the ambari server might have been configured to run on a port other than 8080 so the port to check should be passed down to the agent
> 2) how to handle authentication against the ambari server 8080? Can we just confirm we can connect to the port, even if auth fails? Connect is the test for connectivity, not actual results from the ambari server call.
